Just announcing that the Satoshi Bitcoin Converter has two bits of news:
  1. The Satoshi Bitcoin Converter is now a web app rather than being only a native Android app. This should (a) help resolve issues some people had while loading the current price, (b) should ease hurdles related to apps in the Google Play store, and (c) should allow iOS users to put the app to use.
  2. The web app has its own domain name, link: http://SatoshiBitcoinConverter.com

What's the rationale behind $50,000, $100,000 price predictions?

I don't care about S2F, Tim Draper, or anyone.
Do people even realize that it would take an enormous amount of capital for Bitcoin to reach these highs?
I like Bitcoin because of its technology and ideological message but people who still think that they can still get rich because of it are so delusional.
At $100,000, it would more than double the market cap of Alphabet and Amazon. Do you think that it could be the case for the cryptocurrency that no one uses just because it was a new (and worthless) asset class that broke into the mainstream and made early adopters/exchanges rich? Satoshi, whoever that person is, would be the richest person on the planet? Do you even understand how UTOPIAN this actually is?
You would have a hard time persuading governments to hoard BTC instead of gold. BTC is not going to replace credit cards anytime soon (if ever). You can't even pay for practically anything with BTC in the real world without using third-party apps that convert it into cash.
Sure, the network is growing (along with BTC's intrinsic value) but it's only because mining farms buy more expensive hardware. Mining is actually getting more centralized.
Personally, I don't think that BTC is going to die but even reaching $20,000 would be something insane. I feel like it will mirror Nikkei by failing to reach its peak for a lot of years to come. There will not be another 2017 when Bitcoin surpassed Trump on Google Trends. This type of crypto-mania will not happen again. Even if it does, BTC is unlikely to go far above its previous all-time high.

Is a copy of all AA HEX going to the "origin address"? Scam confirmed?

I've been trying to have an open mind regarding this HEX phenomena. I've done a lot of research on it and have watched hours and hours of Richard's livestreams to try to understand where he's coming from. It basically comes down to "Do you trust Richard Heart" or not. Do you trust him to not dump on the community and destroy the thing he created? Or do you trust his words and his intentions to use his new ETH/HEX wealth for good and to promote the heck out of HEX which might lead to mass adoption and a "number go up" scenario. Think of it the same way as do you trust Satoshi to not dump his million+ bitcoins at any point in time? Earlier today I actually thought the community was over reacting to this whole HEX thing, but then while hanging out in a HEXbad telegram group I stumbled upon some potentially damning info.
It appears that the origin address may be getting a copy of the 500+ million hex that is being minted for users each day through the AA(Adoption Amplifier) - the means by which users are converting their ETH to HEX each day. According to Richard and the HEX website, the origin address DOES get a copy of some of the bonuses / penalties, however it's NOT supposed to also get a copy of all of the HEX that is minted each day. Check these etherscan transactions that show the origin address receiving 500+ million hex from the smart contract.
https://etherscan.io/ "0xf03bb8351687693c359c5a9359bc0b4391496d52561793fc6b2dd23decea2baf" "0x638851c89156d5cc2fcc5ac7d307585a4e2981ea8eee670321f9ac487636789a" "0x543e80561b1bd61da39a49edb887e20b5159cb2aab1aaab2c25a91c1353f492d" "0x8712c547d749343a25c86c95421c356032576cf321dac36f94493778ce206642" "0x71e5283301415600c9cf61bf4c4bae9ecb87d3c69085bb1e634e2e0c9ddf1b07" "0xbdb2fb936bffc51add6c753233e87cabb879291e1a607e9fecf24b34b04af837" "0x53a50f96386b46b2455605f95524e7788eca94fb9dca3e052b7650d91001574d" "0x28fe085e9cdbd55a146b1883a81568b6d87008b7066f3f1f44a766d66c3c99df" "0x0cd193a27de4257f11bd365008679207c0944fb613e98946845c40cbb763247f" "0x8bf775818a92c1f06f64bb02ac91c916d701327f0aedc7907dc0ac6e93d8f449" "0xf43b1b5a6ab13a014d99c63b9746a00f72685d0bc561da6fd87ad1234958e842" "0x5bf8cdf29267ed4d140648dd699a4e52de80998a069ebbb3f914a54632992b0d"
Something is fishy here. Either this is a major bug in the code, or confirmation of the scam.
I've posted this to Richard directly and I expect him to respond to this. I'll update this post as I learn anything new.
for the record - origin moved the today's aa copy (and more from bonuses) to this address and it got staked for ~3580 days
UPDATE! I received an explanation from someone who understand the HEX smart contract better than I do. The 500+ million hex bonus that we see in the transactions above is NOT a copy of the AA going to the Origin Address. It is the daily payout of the WaaS (We are all Satoshi) bonus which is a percentage of all the unclaimed BTC free claim HEX. This bonus is paid out daily to the Origin Address and will be paid out proportionally to all stakers on "The Big Payday" on day 350 or whatever. I admit I don't fully understand it but there is a detailed breakdown here if anyone wants to dive into it.
UPDATE #2 Exposing how the HEX origin address gets paid a massive bonus. TWICE!

Quick question about withdrawing cash from bitcoin atms

Cross post from BitcoinUK
Before you ask - I have used the search bar.
People have stated that the rates are terrible for buying and selling on a bitcoin atm machine. Checked the local bitcoin atms in London using radar map and I must say buying is a rip off, but how about selling? Especially Shitcoin's selling exchange rate looks reasonable, very close or even higher than the current price. What am I missing here?
Example 1 . Example 2 . Example 3 - Worst case scenario for me
Current price (06/12/2019) of 1 btc on google: £5603
Buying price of the machine: £6493.33
Selling: £5790.59
I need to convert my 200> quid worth of bitcoin into cash (am not interested in the holding part). Tried localbitcoins but for some reason (seriously) they didn't accept my ID even though it was extremely clean, no blur, everything is normal but they didn't accept it so I am trying to cash out my bitcoins in another way. I am happy to scan my ID in a bitcoin machine if it asks, (should I though?)
Someone has suggested attending bitcoin meetings, literally I have no idea how I am going to tell people that I am selling bitcoins. Do I HODL a sign in my hand or wear a coin costume?
Any suggestion is appreciated.
Bitcoin wallet: Greenaddress
EDIT: ANOTHER QUESTION. Can I make the transaction with 1 satoshi or will I have to wait hours to get my money?

/r/Bitcoin FAQ - Newcomers please read

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners.

Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Android iOs Desktop

The best Tezos Wallets

The best Tezos Wallets
Tezos is a decentralized blockchain that simplifies formal verification, a method that mathematically proves the accuracy of the code controlling transactions. The Tezos blockchain has its own cryptocurrency called Tezos (XTZ), a cryptocurrency with two main functions – a self-administration system and the ability to form launch contracts using its own programming language – Michelson.
If you decide to convert your fiat savings into Tezos or exchange other cryptocurrencies for XTZ, you may have to make a choice among reliable wallets for this. In this article we will look into the best Tezos Wallets so that can help you understand them better.

Hardware Wallets

Hardware wallets are not liable to spam, viruses, phishing attacks, or malicious of the system. Moreover, they provide a high degree of protection to the private keys. Below is the list of hardware wallets that can be used for XTZ.
https://preview.redd.it/j79t9vbgeth31.jpg?width=800&format=pjpg&auto=webp&s=d828387479fc4a2efed4fc857eb9bdf03f9878e9
  • Ledger Nano S
Nano S is a hard wallet from the product line of Ledger, a French manufacturer company. As all other Ledger products, Nano S traditionally looks like a USB flash drive. But this time, you will need to use the USB cable that comes with the wallet to connect to a computer. Ledger Nano S has a chip that is similar with chips on bank cards or biometric passports. Your private key is stored in an isolated environment and is effectively protected. Ledger Nano S also has a screen on it where you can see each transaction made. In case you lose your Nano S wallet, the account can be easily restored on any other Ledger device. Ledger Nano S supports over 20 cryptocurrencies including Tezos (XTZ).
  • Trezor Model T
Trezor T is the flagship model from the well-known Czech manufacturer SatoshiLabs. Model T has a color Touch-Screen display, an SD port and a quantity of supported coins – XTZ is among those coins. When Trezor T is not connected to the computer, it turns off and disconnects from the Internet. Thus, user funds are stored on the device beyond the reach of attackers. Trezor hardware case is ultrasonically soldered, making it difficult to be restored after being damaged.

Web Wallets

Web wallets can be a simple way to get started investing in cryptocurrency. All web wallets can be used right from a browser without the need of downloading software. Beyond that, many of web wallets offer free mobile apps.
  • TezBox Wallet
TezBox was the first GUI released for Tezos. The wallet was developed by the Tezos community and released during the ICO period. TezBox is available for web, desktop and mobile wallets with its user-friendly interface. Users may be assured that all private keys will be stored on their devices safely due to the secured wallet interface. TexBox is the first wallet integrated with hardware wallets Trezor and Ledger Nano S that gives it the increased security.

As Magnum is a web wallet, it has the extra benefit of being available for nearly any platform, easy of access from any kind of device with an internet browser. Magnum wallet also supports Ledger devices so those can be easily linked to the app.

Mobile Wallets

Tezos has mentioned the wallet on its website and has been audited by an independent external security inspector. As the Tezos CLI needs some level of command line knowledge, it can be quite difficult to use.

How to keep your wallet safe

A cryptocurrency wallet can be regarded as a regular wallet with money, but it has advanced features, which increases the level of risk. Simple rules will help prevent the loss of your own savings:
  1. Do not store large amounts for long periods on wallets that do not provide full control. It is better to store large amounts for a long time only in wallets that provide full control over the private key and, accordingly, over digital assets. This will help protect your coins against fraud and cyber attacks.
  2. Encrypt information and back up private keys. In case of reinstalling the PC or the occurrence of force majeure situations, this will help to restore access to the wallet quickly.
  3. Store secret keys on an offline device. It is preferable to use a platform that is not accessible for hacking via the Internet.
  4. Use reliable antivirus software and update it regularly. This will prevent the leakage of personal data that hackers can use to crack passwords.
  5. Register several types of wallets. It will allow you to distribute your funds and use the most suitable wallet depending on the situation.
If you use your Tezos wallet wisely and do not neglect the precautions, the risk of funds loss will be minimized.

BTC Lightning Network -vs- BCH Coffee Shop simulation

TLDR;

View this gist. It's a python program that runs through various TXN simulations to compare fees of various coins and wallets. Rates are based on late June pricing. Jump to Results section below.

Lighting network simulator

This is a very simple python program that will simulate a few conditions. For the ground work lets set up an Alice and Bob story.
Bob's friend Alice sets up a coffee shop. She is going to start taking cryptocurrency at the coffee shop, so she is set up to accept Bitcoin Cash (BCH) and Bitcoin Core via Lightning (BTCLN). Bob has a substantial holding in both BTC and BCH, though it is all in cold storage in a HW wallet. He does have a Coinbase account but is always very careful to calculate trading fees. So now Bob wants to determine what would be the best way to get ready to move his daily coffee patronage to Alice's shop.
Looking over his past expenses on morning coffee, he decides that 20,000 satoshis (BTC) should be a nice round number for lattes and perhaps 19,000 for coffee. Since BTC is trading at $10,600, his budget in terms of fiat comes out to just about $2 a day. With his budget in hand, he goes about reviewing the BCH and BTCLN payment options. He suspects BTC (mainnet) is too costly since he doesn't want to leave Alice with low priority economical transactions to chase.

Bitcoin Cash

His simplest solution of course is just to move BCH from his HW wallet (cold) to his mobile wallet (hot), but he wants to keep his BTC and BCH accounts fairly balanced and doesn't want to deplete his BCH funds entirely. He also wants to pay Alice in both BCH and BTCLN since she seemed excited about her new Point Of Sale system. He had thought about converting some of his BTC to BCH, though he realizes that there is always a cost for this on Coinbase (usually 0.15%).

Eclair LN Wallet

The next wallet Bob looked at was the Eclair mobile LN wallet. This would be simplest to fund with BTC which of course would have costs in moving funds from his HW wallet to Eclair, and then even more costs opening and closing a channel. He also noted on the github for the project that many LN wallets do not allow fees to be set on channel close operations. This might get costly as market fee rates rise.

Wallet of Satoshi, funded by a BTCLN exchange.

Another popular LN solution is Wallet of Satoshi (WoS). WoS seems like a simple solution since it doesn't have the same constraints on incoming and outgoing capacity like Eclair does. There is also no need to do any complicated channel setup since it is custodial and that is all just handled. Bob does realize that WoS funding options might be costly. He researches ways to load and unload WoS using the FixedFloat exchange as well as the bitrefill Thor channel services.

FixedFloat for BCH funding and withdrawals from WoS

As noted before with WoS, LN transactions are seamless enough, but WoS has no way to convert funds back to BTC. For this we have to use a LN exchange. FixedFloat is a fairly reasonable exchange offering competitive exchange rates and a 0.5% fee. To convert funds from BTC, WoS has offers a comptitive rate of 0.3%, so obviously this is the simplest way to fund the wallet.

Bitrefill for BTC funding

Although not a verify competitive option, the Bitrefill funding option is included here just to see how it stacks up to the others.

Results

I've included two runs of the simluator in LibreOffice format. They should be viewable in Google Sheets, Excel or LibreOffice

Latte (without bugfix)

This simulated buying lattes (20k sat) and compared the cost of using various wallets. Important inflection points that were found:

Coffee (with bugfix)

This simulated buying coffees (19k sat) and compared the cost of using various wallets. Important inflection points that were found. This simulation did assume that the expensive channel close bug in Eclair was fixed:

Here to spread awareness on Health n' Wealth .. Bitcoin is the new born in my practice. Bitcoin was born in 2009(as was my business), year after year, peer after peer, Bitcoin has convinced me it is staying. I committed in 2016 to support the cause... You're probably wondering,"whats the cause?"

  1. I have been a private contractor for 11 years, so my business has "Peer to Peer transactions", and that's the first rule of Bitcoin. This at first is a small statement, give it a lil time, some more information and its significance will grow exponentially
  2. "Proof of Work" will verify that the Custome Consumer actually has the funds in THEIR Private "Bank" Account or a "wallet". This may seem like a redundant statement, because a Visa/ Mastercard or an App such as PayPal, Venmo etc. does that, but in actuality it DOES NOT. You are NOT your "Bank"(unless you have API Keys to a BTC or ETH Wallet, in which than you are a Bank and you are the Bank Teller, greater, manager, CEO and Owner). Most People belong to a Bank with a big or small name, whom which knows everything about you and hold your digital numbers(cash/gold/stocks/bonds) in a vault for you so you can use them any time, any place at your convenience.. OH wait, no they don't, and nor can you. "Not your Keys, Not your Coins" is a saying in the community from Andreas Antonopolous (read his books, watch his videos and listen to his podcasts). Just think in terms of Cash,"Not in your mattress, Not your Cash" even if it were, you'd be subject to your Nations Political Games.
  3. All of this is Public(bear with me) on the "Blockchain". It wont say your name, it'll show numbers and letters which mathematically proves truth and verifies Parties Transfers of Funds. Example: 34786g76g34hb3f487h783 HAS 1.00000000(1 Bitcoin) and TRANSFERS 0.00000001(1 Satoshi) thus NOW HAS 0.99999999 TO h4uer87345hu8387348 whom HAD 0.00000001 NOW HAS 0.00000002. If the sender wanted to send there whole Bitcoin or 700 of them they can do so instantaneously with no 3rd party or CEO needed for verification- oh and over seas without the need of the Nations Government. You may be thinking,"I can do that too", and you could, to a certain extent and much lessor degree. The Bank has your Money. And since they are using it on another platform to make more money, it is NOT in YOUR vault. Even if you had all your cash in your mattress(depreciating in value do to political nationalism) you cant send it to your friend or family far away.. paper gets heavy, oh andf they charge fees to do such transfering and converting...
  4. Right about now most people have said,"this is not for me, I don't need to transfer large amounts of money to someone far away", but WE DO. All over the world we communicate(some of these readers may very well be in another country- with no access to a bank, whom could hold Bitcoin because we have SMART PHONES and send to another Peers Smart Phone"Private Bank Account". Technology, at leased in my years, has been moving onward and upward. If we don't use Bitcoin, our children will. "Cryptography" is safety in the future.
To conclude I'd like to say thank you for taking the moment to read and remind you to google Andreas Antonopoulos.
We are entering a new era. Only constant on this earth is change. Adapt with us. Evolution is necessary.

/r/Bitcoin FAQ - Newcomers please read

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
Some great introductions for new users are My first bitcoin, Bitcoin explained and ELI5 Bitcoin. Also, the following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
Also have to give mention to Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series. Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute. Bitcoin statistics can be found here, here and here. Developer resources can be found here, here and here. Peer-reviewed research papers can be found here. Potential upcoming protocol improvements here. Scaling resources here. The number of times Bitcoin was declared dead by the media can be found here (LOL!), and of course Satoshi Nakamoto's whitepaper that started it all! :)
Key properties of bitcoin

Where can I buy bitcoins?

Bitcoin.org, BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Bank Transfer Credit / Debit card Cash
Gemini Bitstamp LocalBitcoins

Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Android iOs Desktop
Samouari BreadWallet Electrum
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.

The ultimate guide to passive crypto earnings!

I've spent the last couple months figuring out a good strategy to generate some passive cryptocurrency without investing money before a big bull-run starts. As Bitcoin is still fairly low, but cryptos have been risen again in the last weeks, it's best to get in now. I don't have very much time, so I examinated the best-working websites with the littlest time investment and the highest result possible.

Disclaimer: This will be a long post and I'll tell you all the sites I use and how my strategy works. Use it as an inspiration and develop your own working strategy. Skip stuff that doesn't seem to be worth your time or websites you don't like. If you don't like to use a referral-link, just remove the last part of the link. Most websites will give you a bonus when signing up with a ref-link, though and I would appreciate it for the effort I put in this guide.

I assume you have some basic knowledge on cryptocurrencies, a wallet and accounts on Faucethub and Coinpot.

So, let's get started.

Step 1: Claim once a day from stacking up faucets

If you're familiar with faucets, you probably know the moon-faucets that pay directly to Coinpot. They keep stacking up until your next claim, so they are the best and highest-paying faucets if you want to keep your time claiming as little as possible. I suggest you use them at least once a day to accumulate the daily bonus that will really change your game. I do a quick claiming round once in the morning and once in the evening. If you have more time, they are also really worth being claimed more often. For the sake of completion I will include them here:

Moonbitcoin for Bitcoin
Moonlitecoin for Litecoin
Moonbitcoincash for Bitcoin Cash
Moondash for Dash
Moondogecoin for Dogecoin
Bitfun stacking up Bitcoin-faucet that pays instantly to Coinpot

Two new exact clones of the Moonfaucets that pay instantly to Faucethub with no minimum. They also have daily bonus:

Getcoin Bitcoin for Bitcoin
Getcoin Litecoin for Litecoin

And the last stacking up faucet for BTC: Yannik.biz

So yeah, try to claim them at least once a day to maintain your daily bonus. The bonus can really be a game changer on these ones. Claiming them all will take no more than 5-10 minutes every day.

Step 2: Receive daily interest on your faucet claims!

Send your Bitcoin to Freebitcoin and receive daily interest on your balance once you have more than 30000 Satoshis (shouldn't take too long if you put in some effort in the beginning). You can also use the website as a faucet once a hour. It is actually paying well. If you use my link to sign up a new account you will receive life-long +12,5% on your daily interest and +25% on all your claims. If you already have an account, just create a new one with this link and delete your old one as this ref-back-bonus will give you a decent boost on your earnings. Freebitcoin is one of the oldest and most trusted website in the crypto scene!

Step 3: Claim even more cryptos once you have some spare time

Highest-paying sites I found where you can claim every hour along with Freebitcoin are these:

Cointiply: very high paying and they also give you daily interest, but are tied to USD-rates, so you're better off withdrawing your satoshis to Freebitcoin once you reached minimum withdrawal as you would lose satoshis if BTC price continues to rise.

Freedogecoin: Same as Freebitcoin, but with less functions.

Bitsfree: New website with cool design where you can claim once a hour and withdraw to Faucethub at a fairly low amount. Pays pretty well.

Claimbits: Same script as Bitsfree, but pays a bit less and you have to solve three shortlinks once in a while to be able to claim. It's still worth participating in.

Remember: On every claim on these websites you have the chance to win a big amount of cash. So try to use them as often as possible. Unlike the stacking up faucets, with the exception of Cointiply, they don't have a daily bonus, so it's no problem if you ignore them for a while.

Bonusbitcoin: Claim a good amount of satoshis every 15 minutes. Instant payments to Coinpot again.

Click high-paying ads on AdBtc and Dogeads. Another good website for high-paying BTC-ads is Bits-Pays.

Use websites where you can do surveys and all kinds of stuff to earn money that also pay in cryptocurrency. The best website I found that is similar to Swagbucks and has the option to pay cryptos is probably Grindabuck.

Claim your daily bonus at Firefaucet, collect some Autoclaims during the week and run it during the happy hours on the weekend to get most of it. Instant payments to Faucethub.

Step 4: Use semi-passive methods with crypto farming games

There are some crypto games out there that have the ability to build you a decent chunk of passive income after a while. The sites require small tasks you do to earn crypto or credits which you can re-invest in stuff that will generate passive income for you. It takes some effort upfront, but once set up they will passively pay you with no additional effort.Here are my favorites:

Satoshi-Labs: Claim from a faucet every 5 minutes, do surveys and shortlinks and re-invest your earnings in buildings that will generate satoshis for you every hour.

Cryptomininggame: Play a simulated mining game and do missions to level up. As you level up, your earnings increase. This site has a high stacking up daily bonus and can be very profitable once you get to a high level.

Bits-Pays: Has several options to earn passive income. You can play their mining game or buy company shares that will give you dividends. It has a lot of attractive offers for advertisers and very high paying ads and daily bonus, too!

Bitcoinfun: This is a new website that works the exact same as satoshilabs. Once you're into satoshilabs you will also get Bitcoinfun. I see a lot of potential for this website.

Step 5: Fully passive methods

So yeah, let's come to the best part. There are options that require no effort at all! Let's go.

I've already written about sending my satoshis to Freebitcoin for daily interest, but what you can also do is sending some cryptos to Eobot. They are probably the only legit Cloudmining platform out there that has been paying since 2013. You can also claim some GHS there every 24 hours if you set Mining to GHS 5.0. first, which is cool. I like to send some of my altcoins like Doge and Bitcoin Cash to them and convert them in GHS to earn passive Satoshis.

You have probably heart it a thousand times on this sub, but you can also earn Bitcoin by using the two legit autosurfers that pay in Bitcoin by now. This is a fully passive method, just run them whenever you're online.

Getcashfree and Fastcashmining.
Another fully passive website planning to add crypto-payments soon is Radioearn.

Use browser extensions that will automatically generate money for you just for using them:

Presearch: This is probably the best search engine I've ever seen. After installing it will be opened every time you open a new tab. You can customize it, so you can choose from searching via Google, Amazon, Reddit, Wikipedia and much more without accessing the websites first. This is very comfortably and the best part about it: You earn Pre-Tokens for every search, which you can later exchange for BTC.

Surfe.be: A browser extension that shows you some Banners while surfing the web and pays you some money for it. You can disable it at any time and it isn't over-present at all when surfing (I barely notice the banners).

Claim every 24 hours from Mellowads and use it to advertise your ref-links. You can also promote your ref-links on AdBTC, Bits-Pays and DogeAds. Having referrals is another good way to generate some passive income.

Sign up for Mannabase. This is a cool project that aims to create some sort of crypto Universal Basic Income for everyone. After signing up you will need to verify your identity and once they accept you, you'll receive free Manna every week. You can then exchange Manna for BTC or USD. As they have a lot of pending approvals, expect it to take 1-2 months before they accept you.

Conclusion

So yeah, that's basically my main sources and my strategy and I treat it as some sort of site-business. If I am lazy, I spend no more than 10-15 minutes a day to claim the stacking up faucets and daily bonuses on websites and receive my daily interest, payments from Eobot, crypto games and browser extensions anyway. It's really cool to watch your balances, bonus and interest grow over time and who knows? 1$ in Crypto could be 30$ of Crypto in the future. Use this guide as an inspiration to develop your own strategy of acquiring as many Cryptos for free as you can. For me these websites work the best. And I tested a lot of websites.

Additional tips: Use different passwords on the websites and write them all down. It can be a hassle memorizing several passwords. Also create a separate e-mail-address for all the crypto websites. To make it easier handling all the websites, group them in a document e.q. all 1 hour faucets, all stacking up faucets and add links, so you can quickly access them when you want to use this particular group of websites. Be patient at first, your earnings will increase over time.

Feel free to ask me anything, have fun and happy claiming! :)

The best Tezos Wallets

The best Tezos Wallets
Tezos is a decentralized blockchain that simplifies formal verification, a method that mathematically proves the accuracy of the code controlling transactions. The Tezos blockchain has its own cryptocurrency called Tezos (XTZ), a cryptocurrency with two main functions – a self-administration system and the ability to form launch contracts using its own programming language – Michelson.
If you decide to convert your fiat savings into Tezos or exchange other cryptocurrencies for XTZ, you may have to make a choice among reliable wallets for this. In this article we will look into the best Tezos Wallets so that can help you understand them better.

Hardware Wallets

Hardware wallets are not liable to spam, viruses, phishing attacks, or malicious of the system. Moreover, they provide a high degree of protection to the private keys. Below is the list of hardware wallets that can be used for XTZ.

  • Ledger Nano S
Nano S is a hard wallet from the product line of Ledger, a French manufacturer company. As all other Ledger products, Nano S traditionally looks like a USB flash drive. But this time, you will need to use the USB cable that comes with the wallet to connect to a computer. Ledger Nano S has a chip that is similar with chips on bank cards or biometric passports. Your private key is stored in an isolated environment and is effectively protected. Ledger Nano S also has a screen on it where you can see each transaction made. In case you lose your Nano S wallet, the account can be easily restored on any other Ledger device. Ledger Nano S supports over 20 cryptocurrencies including Tezos (XTZ).

How to keep your wallet safe

A cryptocurrency wallet can be regarded as a regular wallet with money, but it has advanced features, which increases the level of risk. Simple rules will help prevent the loss of your own savings:
  1. Do not store large amounts for long periods on wallets that do not provide full control. It is better to store large amounts for a long time only in wallets that provide full control over the private key and, accordingly, over digital assets. This will help protect your coins against fraud and cyber attacks.
  2. Encrypt information and back up private keys. In case of reinstalling the PC or the occurrence of force majeure situations, this will help to restore access to the wallet quickly.
  3. Store secret keys on an offline device. It is preferable to use a platform that is not accessible for hacking via the Internet.
  4. Use reliable antivirus software and update it regularly. This will prevent the leakage of personal data that hackers can use to crack passwords.
  5. Register several types of wallets. It will allow you to distribute your funds and use the most suitable wallet depending on the situation.
If you use your Tezos wallet wisely and do not neglect the precautions, the risk of funds loss will be minimized.

The best Tezos Wallets

The best Tezos Wallets
Tezos is a decentralized blockchain that simplifies formal verification, a method that mathematically proves the accuracy of the code controlling transactions. The Tezos blockchain has its own cryptocurrency called Tezos (XTZ), a cryptocurrency with two main functions – a self-administration system and the ability to form launch contracts using its own programming language – Michelson.
If you decide to convert your fiat savings into Tezos or exchange other cryptocurrencies for XTZ, you may have to make a choice among reliable wallets for this. In this article we will look into the best Tezos Wallets so that can help you understand them better.

Hardware Wallets

Hardware wallets are not liable to spam, viruses, phishing attacks, or malicious of the system. Moreover, they provide a high degree of protection to the private keys. Below is the list of hardware wallets that can be used for XTZ.

  • Ledger Nano S
Nano S is a hard wallet from the product line of Ledger, a French manufacturer company. As all other Ledger products, Nano S traditionally looks like a USB flash drive. But this time, you will need to use the USB cable that comes with the wallet to connect to a computer. Ledger Nano S has a chip that is similar with chips on bank cards or biometric passports. Your private key is stored in an isolated environment and is effectively protected. Ledger Nano S also has a screen on it where you can see each transaction made. In case you lose your Nano S wallet, the account can be easily restored on any other Ledger device. Ledger Nano S supports over 20 cryptocurrencies including Tezos (XTZ).
  • Trezor Model T
Trezor T is the flagship model from the well-known Czech manufacturer SatoshiLabs. Model T has a color Touch-Screen display, an SD port and a quantity of supported coins – XTZ is among those coins. When Trezor T is not connected to the computer, it turns off and disconnects from the Internet. Thus, user funds are stored on the device beyond the reach of attackers. Trezor hardware case is ultrasonically soldered, making it difficult to be restored after being damaged.

Web Wallets

Web wallets can be a simple way to get started investing in cryptocurrency. All web wallets can be used right from a browser without the need of downloading software. Beyond that, many of web wallets offer free mobile apps.
  • TezBox Wallet
TezBox was the first GUI released for Tezos. The wallet was developed by the Tezos community and released during the ICO period. TezBox is available for web, desktop and mobile wallets with its user-friendly interface. Users may be assured that all private keys will be stored on their devices safely due to the secured wallet interface. TexBox is the first wallet integrated with hardware wallets Trezor and Ledger Nano S that gives it the increased security.

  • Guarda Wallet
Guarda Wallet is available as a Web, Mobile and Desktop Wallet and a Chrome extension. It supports more than 40 coins and 10,000 tokens as well as XTZ. The web wallet enables to access cryptocurrency from any modern browser, the website itself looks presentable and made convenient to use. Using the mobile wallet, you can create a new wallet or import an existing one. Besides the common functions such as storage, deposit/withdrawal of cryptocurrency, users can instantly buy the exact amount of cryptocurrency using a bank card or exchange coins and tokens.
  • Magnum Wallet
While Magnum is a multi-asset wallet, one of the best known assets it supports is Tezos (XTZ). Being a light wallet, you do not need to download the full blockchain of any of the cryptocurrencies it works with. The wallet does not keep users’ personal information. As Magnum is a web wallet, it has the extra benefit of being available for nearly any platform, easy of access from any kind of device with an internet browser. Magnum wallet also supports Ledger devices so those can be easily linked to the app.

Mobile Wallets

Mobile wallets are used on your smartphone via an app. Similar to Apple or Google Pay, you can use mobile wallets when shopping in physical shops as cryptocurrencies become more popular and acceptable. Mobile wallets may be safer compared to online wallets and also be easy to use on the go.
  • Trust Wallet
Trust is a wallet for tokens of ERC20 standard, tooled for mobile devices. It offers simple installation and affordable feature set, that does not require additional user skills and abilities. Trust Wallet and Binance are working on new features, including market monitoring, user networks, test networks, and deep integration with the Binance infrastructure. Trust Wallet already supports Tezos as well as other digital currencies.

  • AirGap Wallet
AirGap is a wallet, that allows you to keep your cryptocurrency securely on your mobile. AirGap is a system with two device access: you can use your old mobile device as a hardware wallet using the AirGap Vault app to keep the private key there; while your working smartphone will have the wallet itself. The connection occurs with QR codes, this ensures a genuine one-way communication between AirGap Wallet and AirGap Vault. This implies that no private information ever leaves the air-gapped old phone. Besides Tezos, AirGap supports diverse amount of cryptocurrencies.
  • Tezos.Blue Wallet
In spite of being a lightweight wallet, Tezos.Blue does not scant on security or its features. It is an original app and that is why it gets strong protection straight from the operating system. Using the Tezos.Blue you will have actual updates from the network for a truly live operational comfort. Tezos.Blue is also available in a desktop version. Tezos.Blue is also available in a desktop version.

Desktop Wallets

Desktop wallet can be downloaded and installed on a computer. Desktop wallets may be safer if your computer is not, or more preferably, has never used the Internet connection. Desktop Wallets are perfect for storing large amounts of crypto that you don’t want to use on an everyday basis.
  • Atomic Wallet
Atomic is a convenient, easy to use and safe cryptocurrency wallet, that receives the preferences of many users around the world. It is a decentralized multicurrency wallet that is known in the crypto community for supporting more than 500 cryptocurrencies including Tezos. The primary goal of Atomic Wallet is not just to store cryptocurrency, but also to create a strong ecosystem with many functions.

  • Atomix HD Tezos Wallet
HD wallets (hierarchical deterministic wallet) are the wallets that use a single 12 or 18-word mnemonic phrase that is used to identify following addresses and private keys in a wallet software. Atomix is HD wallet that supports Tezos, it merges benefits of decentralized and centralized exchanges. With Atomix, all private keys are kept encoded on the computer. No identity verification or registration is required to use the wallet.
  • Simplestaking
Simplestaking is Tezos focused wallet being a web app and desktop app with support for hardware wallet Trezor Model T. The wallet is developed using NgRx state management and Angular framework.
  • Galleon Tezos Wallet (Tezori)
Galleon is a smart open source wallet for XTZ that supports both hardware and software wallets on Windows, Linux and Mac. It was developed by Cryptonomic and funded by the Tezos Foundation.
  • Tezos CLI Wallet
The Tezos CLI wallet can be used by those users who have some coding understanding while it requires the use of command lines. Tezos has mentioned the wallet on its website and has been audited by an independent external security inspector. As the Tezos CLI needs some level of command line knowledge, it can be quite difficult to use.

How to keep your wallet safe

A cryptocurrency wallet can be regarded as a regular wallet with money, but it has advanced features, which increases the level of risk. Simple rules will help prevent the loss of your own savings:
  1. Do not store large amounts for long periods on wallets that do not provide full control. It is better to store large amounts for a long time only in wallets that provide full control over the private key and, accordingly, over digital assets. This will help protect your coins against fraud and cyber attacks.
  2. Encrypt information and back up private keys. In case of reinstalling the PC or the occurrence of force majeure situations, this will help to restore access to the wallet quickly.
  3. Store secret keys on an offline device. It is preferable to use a platform that is not accessible for hacking via the Internet.
  4. Use reliable antivirus software and update it regularly. This will prevent the leakage of personal data that hackers can use to crack passwords.
  5. Register several types of wallets. It will allow you to distribute your funds and use the most suitable wallet depending on the situation.
If you use your Tezos wallet wisely and do not neglect the precautions, the risk of funds loss will be minimized.

Grin symbol

I just saw this poll on Twitter: https://twitter.com/grinMW/status/1087447097211842560 and realized my favorite crypto symbol is leading there in the voting by a wide margin. My thinking with Bitcoin was that, in time, we're going to need a symbol for the lowly satoshi. I've been pushing for the katakana "shi" or "si" symbol for years now. That symbol is the "shi" in Satoshi. I advocated for it to be adopted as the Bitcoin satoshi symbol (https://www.reddit.com/Bitcoin/comments/3egrjk/satoshi_symbol/), stuck it on the blockchain (http://br549.mywebcommunity.org/why.htm), and made it the icon of the Satoshi Bitcoin Converter app (https://play.google.com/store/apps/details?id=com.satoshi.bitcoin.converter&hl=en_US).
So, when I saw the "shi" symbol leading on this Twitter poll for Bitcoin 2.0, AKA Grin, I thought that was pretty awesome.
My suggestion...vote for the "shi" symbol and send a message. Yes, it's not the most currency-like symbol in a traditional sense, but THAT'S THE POINT! Cryptocurrency is all about disruption. It's about rocking the status quo and blazing a new and better path, rather than going with the more-well-trodden path simply because that is more acceptable and because that's more akin to what we're all used to. Why even bother?
Also, the "shi" symbol has two intrinsic and intuitive benefits...(1) it holds a left-to-right reading that implies an upward growth, like a double-winged bird soaring skyward, and (2), it signifies a grin! A sideways, clever, independent, and fun grin!
Symbols matter! Symbols, even one's that initially seem different, eventually stick. And when they stick, they become the implication that they suggest.
This is not hard!

Anti-FUD: The BIP148 enforcing client - a walkthrough.

There seems to be a lot of FUD going around surrounding https://github.com/uasf/bitcoin/tree/0.14 <--that little guy. I'm a programmer, so let me walk you through what, exactly, is changed, and how you can verify what changes for yourself.
So, to get started, click on the 'Compare' button just below the green button that says 'clone or download'. link
This shows you every single change that has been merged between bitcoin core, in the 0.14 branch (the branch that was used to create the 0.14 Core client many of us use) and this repository's version of the 0.14 client, which requires any blocks after August 1, 2017 to support Segwit.
So, let's go through the page, top to bottom, and explain what it is telling you.
19 commits 4 files changed 3 commit comments 3 contributors 
That tells you that 19 times someone has changed something in the code base, in total, 4 files were changed by those 19 commits, 3 commit comments were made (think of these as replies to a thread on reddit), and 3 people total have made contributions to the code differences represented below.
Below that is a list of what commits were made on what day. You can click on the second column (BIP148 / Update client name to Satoshi BIP148 / etc) to see what changes were made in that version (compared to the version before it) specifically.
Scroll down until you hit
Showing with 19 additions and 5 deletions. 
This is where the 'fun' (programming) begins.

src/clientversion.cpp

-std::string FormatSubVersion(const std::string& name, int nClientVersion, const std::vector& comments) +std::string FormatSubVersion(const std::string& name, int nClientVersion, const std::vector& comments, const bool fBaseNameOnly) 
Red lines, which always start with a minus sign, means that line was removed from the file. Green lines, which always start with a + sign, mean that line was added. "But the line wasn't removed, just some stuff was added to the end!" Correct! This is a 'diff-ism'. Diff being the name of the program used to show differences between a file. Diff doesn't highlight just the part of the line that changed, it highlights the entire line, and leaves it to you to spot the changes in the line.
From the above, we can see a parameter was added to the end of the line. "But what does the line do!" Well, what you're looking at is a function declaration. What is a function? Well, imagine you wanted to build a robot to make sandwiches for you. You could make the sandwich yourself, but it's easier if an automated system does it for you. The function is like the robot; you put a specific set of tasks into the robot's programming, give it a specific set of inputs (bread, knife, meat/cheese/spreads/etc) and it returns the resultant sandwich. The way to read the declaration is this:
std::string FormatSubVersion(const std::string& name, int nClientVersion, const std::vector& comments, const bool fBaseNameOnly) 
  1. std::string The first argument is the return type of the function. In this case, a C++ string.
  2. FormatSubVersion This is the name of the function
  3. (const std::string& name, the first parameter of the function, since it is unchanged from Core, and unmodified by other changes in the file, I will not bother explaining what it does.
  4. int nClientVersion, Second parameter to the function. Same thing, original, unmodified, skipping.
  5. const std::vector& comments, Parameter 3, unchanged, skipping.
  6. , const bool fBaseNameOnly) Parameter 4, 'const bool' means two things: 1) we cannot change the value of this variable in the code. 2) it's a 'bool' type, which is short for boolean. It an either be true or false, those are the only values it can ever have. What does it do? Let's keep reading.

std::ostringstream ss; 
That's important for later, make note of it.
if (!fBaseNameOnly) ss << "UASF-Segwit:0.2(BIP148)/"; 
The above is the change uses the newly minted parameter 4 to add a bit of text into the output stream. Specifically, the string "UASF-Segwit:0.2(BIP148)/" is tacked on to whatever is ahead of it in the output stream. The net result of this change is that clients using this code will report their client version as '/Santoshi:0.14.0/UASF-Segwit:0.2(BIP148)/' instead of the standard value of '/Santoshi:0.14.0/'.
File complete! Next file.

src/clientversion.h

Within C or C++ programming, you have the concept of 'code files' (ending in .c or .cpp) and 'header files' (ending in .h). Strictly speaking, any code can be in either file and the compiler will figure it out (assuming you give it enough information to do so). However, programming conventions exist. Since I assume the readers of this post are (largely) not programmers, I won't bore you. It's a convention used for sanity only, and it is a convention followed by the bitcoin source code. In general, program code that 'does stuff' goes in .c and .cpp files, and the code needed to tell the compiler (compiler = the thing that converts these text files into a program) where to 'find stuff' goes into .h files.
-std::string FormatSubVersion(const std::string& name, int nClientVersion, const std::vector& comments); +std::string FormatSubVersion(const std::string& name, int nClientVersion, const std::vector& comments, bool fBaseNameOnly = false); 
Well, because this is the exact same function call we just talked about in the previous section, I'll skip going through the parameters one by one, and instead focus only on the change: , bool fBaseNameOnly = false).
"WAIT! It has 'const' before bool in the .cpp file! That's bad right!?" No. The compiler will see const in the .cpp file and mandate the variable be const.
"WAIT! Here it says '= false' and in the .cpp file it doesn't!" Again, not a problem. Remember how I said some code goes in .c/.cpp files, and some in .h files? Well, this is a case where which file contains what code actually does matter. Basically, you can't set a default value for a parameter inside a .c/.cpp file. You can only do that in a .h file. So...that's 100% correct. Here is the souce code for a quick little program to see this behavior:
--test.cpp--
#include "test.h" #include  #include  int main() { function(); } int function(const bool tmp) { tmp = !tmp; } 
---test.h---
int function(bool test = false); 
--If you tried to compile this, you'd get--
g++ test.cpp test.cpp: In function ‘int function(bool)’: test.cpp:12:6: error: assignment of read-only parameter ‘tmp’ tmp = !tmp; 
In this case, 'read only' means 'was declared const'.
Remember how a 4th parameter was added in the code above? Well, you have to tell the compiler to expect that parameter, which you do here, in the header file. That line of code tells the compiler to expect the 4th parameter. It also sets the default value of the parameter, should the caller not specify it, to be false.
Thus, you can call this function two ways:
  1. FormatSubVersion("Test", 99900, std::vector())
  2. FormatSubVersion("Test", 99900, std::vector(), true)
Using method 1 would result in a User Agent string of '/Test:99900/UASF-Segwit:0.2(BIP148)/', because the program uses the default value of 'false' and so it sticks in the bit about BIP148 support. Using method 2 would result in '/Test:99900/' "Wait, wait, how did you figure that out?" Look here, scroll to the bottom (line 88) and that is the FormatSubVersion function we went over above. All you do is built the string in steps as you read the code:
  1. Line 90: ""
  2. Line 91: "/"
  3. Line 92: "/Test:99900" {the 'Test' comes from the 'name' parameter, parameter 1. The : is statically coded (<< ":" <<) and the 99900 comes from nClientVersion, parameter 2}
  4. Line 93: From the function call, we see that parameter 3 is initialized 'std::vector()', this is an empty vector. If the vector had anything in it, it would look like this: std::vector('a')
  5. (because the if statement in line 93 fails, we go to: ) Line 101: "/Test:99900/"
  6. Line 102: (are we doing a version with or without the 4th parameter set to true?)
  7. Line 103: (if parameter 4 is false, line becomes "/Test:99900/UASF-Segwit:0.2(BIP148)/"
  8. Line 104: Convert the 'ss' variable to a standard C++ string and return the that string to whatever asked this function to be run.
SO, in total, this function literally just creates a string. Much like the robot-sandwich example, you give the function a client name, version, and list of comments and it builds you a string containing those things.

src/test/util_tests.cpp

This file is part of the automated testing for bitcoind/bitcoin-qt. When you compile the software, you'd typically run 'make check' before installing the software, to ensure that your changes didn't break anything and that your compile didn't go wrong. With the effort I've put into explaining the change to FormatSubVersion in the past two section, I believe you can now see that the only change made to this test is to ensure that the newly added code performs as expected.
That said, there is a 'defect' in this code. He should not have removed the 3 existing tests. He should have added 3 new tests. That way he'd have both 'positive' and 'negative' test case coverage. That said, it isn't something to fret about.

src/validation.cpp

All right, finally, the big file where all the cool shit happens!
+ // BIP148 mandatory segwit signalling. + if (pindex->GetMedianTimePast() >= 1501545600 && // Tue 1 Aug 2017 00:00:00 UTC + pindex->GetMedianTimePast() <= 1510704000 && // Wed 15 Nov 2017 00:00:00 UTC + !IsWitnessEnabled(pindex->pprev, chainparams.GetConsensus())) + { + // versionbits topbit and segwit flag must be set. + if ((pindex->nVersion & VERSIONBITS_TOP_MASK) != VERSIONBITS_TOP_BITS || + (pindex->nVersion & VersionBitsMask(chainparams.GetConsensus(), Consensus::DEPLOYMENT_SEGWIT)) == 0) { + return state.DoS(0, error("ConnectBlock(): relayed block must signal for segwit, please upgrade"), REJECT_INVALID, "bad-no-segwit"); + } + } + 
The entire section is newly added. Anything it does will be 'in addition to' whatever is already done. Let's go through the change line by line:
"Ok, but what about 1501545600? How do we know that?" It's an epoch timestamp. Google 'epoch converter', copy-paste that number in, convert to UTC, and you'll see it is correct for what the comment says it is.
The '&&' at the end of the line means 'and'. So in this case, 'if the mean age of the past few blocks is greater than or equal to and ...'
You can see proof of this claim in the tests written in src/test/versionbits_tests.cpp lines 277-281. line 277 creates an 'old format' block, then (line 279) checks that the ComputeBlockVersion function works, then verifies that the bitwise-and function returns TOP_BITS, as expected.
If you are concerned that more might be needed to reject a block, simply view src/validation.cpp on line 1892 and see that standard bitcoin Core code rejects blocks in the same way as the SEGWIT patch does.
"So wait, what is the total requirement to reject a block again?"
  1. If the mean age of the past few blocks is greater than or equal to AND the mean age of the past few blocks is less than or equal to AND the previous block did not show that Segwit was in 'active' state:
  2. If all of the conditions in step 1 are met AND the block either does not support BIP9 messaging, or does not signal support for SEGWIT
  3. Then it will be rejected.
"So wait, what happens after the first segregated witness block pops across the network? Hasn't that already happened?" No. Blocks that support segwit have come across the network, but in order for IsWitnessEnabled to return 'true', the SEGWIT state would need to switch to 'active' (see BIP9 spec), which is the final state of any proposal, and the point at which the setting is considered an accepted part of the blockchain.

Conclusions

So, you see, no muss, no fuss. The day-1 bug where the logic was backwards has been fixed. There is nothing to fear. Feel free to ask questions and I'll explain them over the next few hours/days as I am able. I'll try to talk to your level if I can. I like teaching in general and abhor ignorance in all its forms. Understand: ignorance strictly means 'not knowing', rather than the typical 'negative' connotation it gets in English speaking society. I would like everyone to realize just how simple this UASF patch is and that the FUD surrounding it not being 'verified' is absolutely a bad joke.
edit: Logic fix thanks to Phil. Like shaolinfry, I had my negated logic backwards. Oops.
