FUD Friday: Greg Maxwell drops the hammer on Haskell and Rust

My first OP was dedicated to debunking trivial EITN FUD, so this time I'm going in the opposite direction and asking others to debunk or support what one of Bitcoin's top math/crypto/compsci gurus says about Cardano's chosen languages.
Thanks to both u/nullc and u/ataraxiaceleste for opening and expanding the discussion.
Courtesy of BitcoinTalk: Thoughts regarding use of Rust and Haskell for building a blockchain
Gmax responds:
Performance and memory usage are both security critical in consensus systems. It's difficult (impossible?) to write Haskell which is all three performant, predictable in its memory usage, and idiomatic-- at least for some sufficiently strict requirements in performance and memory usage.
Rust is a lot like C++. In theory, it's easier to write rust code that lacks particular classes of bugs than in C++. However, no one using C++ uses the entire language and the various subsets people use also largely avoid various kinds of bugs. Not as rigorously as rust, particularly because its hard to verify you're using the subset of C++ you're intending to use.
In Bitcoin we've found that the kind of bugs that rust guarantees the absence of have been uncommon.
I've personally found that the rust code I've encountered online has often been low quality to extremely low quality-- often throwing panics on the slightest unexpected input or usage, or suffering from incorrect results due to integer wraparound (which in theory debug mode would catch, but it runs so slow as to be completely unusable on many codebases). I'm unsure if this is a property of the language itself (e.g. does the syntax lead to greater faults), user's expectations of the language (sloppy work because they expect things to be 'safe'), or the useapplication (e.g. are people that redo stuff "but in rust" less experienced programmers?).
Given that experience I would not place a bet right now that rust currently lowers the rate of serious defects in large programs developed by experienced teams compared to C++ with modern practices. However, if I had to use software written by inexperienced developers I suppose I would probably prefer they use rust to C++...
The rust ecosystem is also immature and unstable-- it's not uncommon that any random code you get requires some bleeding edge new compiler. Rust also largely imitates the extremely security-toxic software distribution model of ruby and javascript-- it's common for a rust package to have a dependency graph of hundreds of assorted packages, any of which could backdoor your system. It's possible to use rust without using the packaging ecosystem, but doing so is more of a challenge.
Rust and C++ also have no good facilities for formally reasoning about the behaviour of programs (beyond things like the borrow checker in rust). But C++ is a superset of C and there are tools to rigorously prove things the properties of C code, which means you can write components of C++ programs in C and formally prove things about them. You could do the same with rust+c but C++ and C share a lot more syntax and behaviour.
In the world of open source Rust and Haskell both have an additional limitation that the community of developers and reviewers for these languages is smaller than that of C++.
Please note that however much I tend to defer to his opinions (per Adam Back's guidance that when one disagrees with Greg about technical matters they are probably wrong), I must reconcile that deference with respect for the IOG team's galaxy brains. Negative appraisals of Rust and Haskell aren't going away, so IMO it behooves the Cardano community to get a grip on the most valid criticisms and try our best to stay ahead of them.
On a lighter note, the Monero sub has been having a lot of fun in their weekley Skepticism Sundays and we are overdue for our own version, as previously suggested months ago by u/velvia695 at https://www.reddit.com/cardano/comments/de1mqg/suggestion_skepticism_sunday_like_monero_has_but/ .
Let's keep it educational and really do our best to limit use of ad homs to zingers and puckish banter rather than as a subsitute for actual arguments!

Network effect doesn't explain Bitcoin dominance : technical arguments for Bitcoin Maximalism

I often saw some Bitcoiners counter the altcoin shillers with the following argument: "Bitcoin is the first so it has the network effect, so your altcoin will always worth less"
This is not totally wrong but I think this argument is bad. Using it implies implicitly that you admit that Bitcoin is technically less capable than altcoins with their higher transaction rate, fast blocks, instant confirmation, without fees and smart contract support....

And this is WRONG ! Bitcoin price is higher, because Bitcoin is already TECHNICALLY BETTER than any other altcoin and not because of network effect. In 2017, Bitcoin dominance was lower, some altcoin reaches almost the same level than Bitcoin. So network effect is not what prevents an altcoin to take the lead but it is the fact that almost all altcoin that pretend to be better than Bitcoin are technically flawed.
Why ? They use bigger blocks, DAGs (Directed Acyclic Graphs, like used in IOTA or Nano) or wtf they created to disturbe you and make you believe they are better than the good old Bitcoin blockchain. But they have at least one of these two weak points: validation time oand bandwidth.

If they use biggefaster blocks, validation time of block is higher and so block propagation is slower. Less nodes can operate as they may not be able to validate blocks fast enough to keep up with the tip of the chain. You end up like Ethereum that has less and less full verification nodes leading to centralization of the network.
If they use DAGs, they achieve consensus through a "proof-of-stake" vote and always at the cost of bandwidth (quadratic cost in number of node, linear in transaction rate). DAGs are often presented as "each node has its own ledger" but the reality is that the only global ledger you should trust is the complete DAG of the ledgers of each node. Only servers with a shitload of download bandwidth can maintain it as debunked here and here. To not look (in fact be) centralized, some DAG altcoins doesn't, opening the door to history rewrite by buying account that owned a big stake before and still use a lot of bandwidth to reach consensus. Bitcoin just add 80 bytes of proof-of-work data on a block of 1-2MB to achieve it and protect from history rewrite, almost zero cost for the network (that's why we pay fees to miners who carry the cost).
You only have those problems when it reaches a critical level of usage and only then we can see how much those limits where ignored. Until now, very few altcoins reached the limit (maybe Ethereum, and IOTA shows us it is centralized already by stopping the network)
Bitcoin has the highest price because Bitcoin is technically the only possible decentralized king (and a centralized cryptocurrency worths nothing). Yes maybe 1MB limit was too conservativ, yes fees are higher, yes 10 minutes is slow. But if everyone wants their coffee payment to be settled onchain, 1MB or 8MB or 32MB each 10 minutes, minutes or secondes will never be enough while it is a big difference for the network health. You only need the blockchain for settlement, for payment you have Lightning Network that can already destroy PayPal's transaction rate.
So next time you feel convinced by an altcoin that pretend to be better than Bitcoin while being decentralized by design, evaluate the requirement to be a fully validating node and what the overhead of bandwidth needed to achieve consensus. The chances are high that they didn't take care of one of these two issues and end up centralized or broken. You don't need the network effect argument.

I wrote an offline Bitcoin block explorer that loads data from Bitcoin Core and allows you to explore the blockchain on your PC

Dear /Bitcoin, I wrote a set of tools to import data from .bitcoin/blocks/blkXXXXX.dat files into databases and allow you to explore the blockchain on your own PC by running ad-hoc queries of all the main Bitcoin Core data structures including blocks, TX's, inputs, outputs, addresses and more.
It's written in C++ and uses Bitcoin Core itself to read the data, so it's always 100% compliant with the latest Bitcoin release. I abstracted away the database functions, so you can implement "drivers" for any other DB system. I've been playing with it on MySQL but perhaps others would prefer Neo4J or Cassandra for nosql graph analysis.
Once the data is loaded, you can run any database query against it.
I implemented a simple reference Python interface to it so you can play with the blockchain. I made this outer layer in Python but any other language can be easily plugged in, including big data analysis systems like Spark or Hadoop.
Some stuff you can do with it:
While loading the block files it does some additional work :
Addresses, TX's and all other data structures are decoded by Bitcoin Core itself. The C++ Toolbox links to Bitcoin Core and uses the canonical implementation, so the loaded data is accurate. The Python reference implementation is almost 100% independent from the C++ code (except for configuration code which shares the same parameters and config file as the C++ Toolbox).
Released under the MIT license.
I hope you like playing with it!

HEX Unique features

HEX is the principal endorsement of store on the blockchain! HEX pays Trustless Interest with no counterparty chance. Given programmable cash the principal program ought to be premium.
Pays holders rather than diggers. Staking HEX resembles getting free mining equipment and power. Bitcoin and HEX correlation
No Satoshi (on the off chance that he doesn't guarantee in 50 weeks) or Mt.Gox dumping on you. No swelling bug conceivable like bitcoin has had. Unit predisposition fixed. Progressively disseminated mining environment. Whale punishment which gives whales coins to stakers, and so forth.
Around 12 million or more of the 18 million all out BTC worth of HEX cases will be given to the stakers on day 353 by shares. What's more, It gets duplicated by the Viral and CriticalMass selection extra multipliers which can build it up to 3x. The offer cost just goes up.
Stakers that end stake early or late compensation faithful stakers. Longer stake submit pays 20% more every year, up to 3x shares, (halfway years are fine). Lower charges, lower swelling. Referral program. Organizer is a showcasing master with a crowd of people. Early adopters get paid amazingly well.
20% Speed reward tumbling to 0% during the fifty weeks. Unclaimed coins paid to stakers 2% every week for 50 weeks. Consistently you don't guarantee, another person gets your coins. Minimum amount and Virality rewards increment payouts to stakers so they make progressively HEX the more individuals that guarantee, than if less individuals asserted, despite the fact that they get unclaimed coins on day 353. Each pumpamental to bolt up supply, increment reception and cost.
Hex has a lower expansion rate than Bitcoin, much after the rate was sliced down the middle twice in its 10 years. The swelling is additionally deferred, in light of the fact that it's just paid on finished stakes, and stakes can most recent 10 years. Failure to exchange staked coins builds the estimation of unstaked coins, and chance that some will early endstake and take care of punishments to faithful stakers.
Trustless Interest.
Suppose you need to make more bitcoin on your bitcoin. What are your alternatives? You could loan your coins out and face the challenge they're not returned, or you could have a go at selling your coins for mining equipment and want to get more coins back later. Bunches of individuals have lost cash attempting either.
Counterparty hazard in Bitcoin ventures.
To acquire enthusiasm on their Bitcoin, most clients send them to a brought together outsider, for example, a trade. There, coins can be acquired to "short" the market. Merchants acquire the coins to sell, in the expectations that they can rebuy them less expensive before they need to return them, along these lines benefitting from value diminishes. These brought together gatherings are security openings that are frequently hacked, annihilate protection, or acquaint expenses on the off chance that you need with get your assets out. Billions of dollars in coins sent to trades or loan specialists have been taken. Not your keys, not your coins.
These concentrated outsiders and brokers are so essential to clients looking for yield (making interest) that the organizations themselves have made more benefit on Bitcoin than its originator. A huge number of dollars of significant worth has moved into the pockets of brokers. HEX fixes this.
This replaces these outsiders with a trustless distributed to framework. Rather than sending your HEX to a trade so they can loan it out for your sake to procure enthusiasm for you, you simply lock it in same brilliant agreement that stamped all the HEX in any case, and it credits you intrigue. In case you're given programmable cash, the principal thing you should program is premium.
HEX pays enthusiasm to stakers rather than excavators.
A few clients take a stab at mining to make more digital money. Rather than sending your cash to a remote super corp to purchase mining gear which appears late, utilized, or never by any stretch of the imagination, you can avoid the deteriorating resource and power bills and simply stake your coins.
HEX is the primary digital currency with a graph of future sellable stockpile (lapsing stakes after some time.) This makes sure about purchasers trust in future estimation of their speculation.
HEX has Speculative Stickiness.
Typical cryptographic forms of money have: Price, hash rate.
HEX has: HEX value, Share cost, Directly influences staker benefit per share: % of supply staking, Average stake length, Average stake size, stake termination diagram after some time, early and late end stake punishments.

Blockchain Training Center In Noida
With the neck-to-neck competition in the corporate world, the industry needs to keep up with the latest trends and technology. This increases the demand for professional industry specialists who need to be equipped with the latest and advanced courses to become more competitive and bankable, such as blockchain training in the industrial world.
Blockchain technology has made a big impact in recent years by maintaining public records, healthcare areas, or real estate guarded records and maintaining safe and clear financial transactions.
Let's understand blockchain technology more
A blockchain is actually a chain block list that binds to one another with the help of cryptography codes. Blockchain technology is considered reliable, fair and secure, enhancing the demands of professionals. Blockchain Training Center In Noida
There are many blockchain courses online courses available with major academy acade online academies; NewTime (an academy online academy) tops them all. Ironically, with the demand for blockchain developers, there is a dearth of professionals who are launching a huge pay package and career in the IT world.
Blockchain eliminates the interference of operators in transactions such as governments and large institutions. So making it an open source network that is easily accessible. Blockchain Training Center In Noida
Bitcoin is the first form of digital cryptocurrency that has recently been accepted and globally blocked by its equivalent value against paper, which varies according to their geographical location.
The second most commonly used cryptocurrency is Ferrium, which uses technology as it allows its users to create their own wallet using their network to avoid the coding processes required to wallet. Blockchain Training Center In Noida
Blockchain training teaches a number of topics that understand the key concepts of blockchain. Concepts such as Bitcoin, Ferrium, etc. are described in minute detail. The meaning of blockchain and blockchain concepts is taught in-depth in blockchain training. It gives you a deeper understanding of what Bitcoin is and how it works. One also has an understanding of how ferium is easily used in bats.
Real-world examples are used to teach concepts, making content easy to understand. A comprehensive understanding of blockchain programming can be gained by examining a course from the best institutions, such as the Nitam.
Blockchain training is very important for software professionals, kids and others considering the changes made to the blockchain techno-world.

Dash had a planned instamine - It was no accident. Today, the founders hold a huge amount of the Masternode Network and continue to reek profits off those who don't know.

I'm going to start this thread with a tl;dr and a few sources to back everything up. Then, I will go into detail and recreate a thread dnale0r posted a few years back.
.
  1. The founders of Dash could hold up to 25% of all current Dash in existence [1] [2] [3]
  2. The founders decreased the max circulation to give them a larger % hold on the network [1] [2]
  3. Masternodes were created to allow the founders to continue gaining from their instamine [1] [2]
And for completeness' sake, Dash Admitting the Instamine Happened (Just so the trolls can't deny it)
.
.
The Timeline
.
.
Proof of instamine
Look at these beautiful graphs that show how much Dash was being mined at the beginning.
4 hours after launch, 1 million Dash was mined
2 days after launch, 2 million Dash were mined, then growth very abruptly plateaus.
.
The part that doesn't add up
So here we have a coin, that no one really cares about because there was little information about it at the time, so you would obviously want to let as many people use it as you can.
Except Evan only made the coin mineable on Linux.. Which is a bit odd seeing as in January 2014, only 1.13% of computers ran Linux in any form.
.
The Bombshell
From the List of nodes that were mining Dash at the very beginning, it turns out 50 OF THEM were Amazon AWS and another 50 where Microsoft cloud computing. This makes up 100 out of 124 miners on the Dash network at the time - And considering how many shitcoins are out there, who would have the foresight to set up 100 cloud computers to mine the coin? (this source suggests 115/124 were cloud hosted)
.
I can go on for a long long time but everything left I have to say is in the many sources I left behind. I'm cutting it short here and letting everyone come to their own conclusions.
And by the way, there are some very honest and legitimate Dash supporters. I was discussing the instamine with one of them a couple days ago and he was very passionate about the project - Don't hate the community, hate the coin.
Peace xo
Edit: I'm working on giving the other side of the story in the comments, this time attacking Monero. Stay tuned
Edit2: Is Monero the Culprit?
Edit3: I seem to have offended a lot of Dash friends. Hopefully one day they'll try to back up their claims instead of trying to discredit my sources.
Edit4: This is a story well known to Dash friends, so don't be surprised if all the comments are just people shilling Dash. That's the reason I posted this, and hopefully next time someone brings up Dash you'll be equip with knowledge and won't fall for it.
Edit5: I've never seen tempMonero lose his shit before

Which type of curren(t) do you want to see(cy)? A analysis of the intention behind bitcoin(s). [Part I]

Bitcoin was released to the world in 2009 by someone (or a group) who authored a technical whitepaper, released the source code to the protocol and commented on a few p2p forums and mailing lists under the pseudonym Satoshi Nakamoto for a few months prior and a few years afterwards before leaving the project. The project was left in the hands of Gavin Andresson who was another cryptographer that satoshi communicated regularly with on the forums and had been one of the first people involved in the project. Some time after satoshi left, one of his accounts was allegedly hacked and bitcointalk (the primary forum) itself was hacked so a meme kind of emerged that satoshi wouldn't be able to post again from his accounts or that posting from them would be dubious. In 2016 an Australian by the name of Craig S Wright was exposed by Wired and Gizmodo as potentially being the inventor of bitcoin. Craig then signed privately for Gavin Andreson, Jon Matonis but then when he was supposed to cryptographically sign to a journalist the method performed did not hold up to public scrutiny because he could have copy pasted a fragment from an earlier known signed message from satoshi and not generated it himself with the private keys. This cast a lot of doubt from many on the man's claims and he published an article saying he wasn't brave enough to sign.
Since then the term cryptocurrency has blown out massively to include anything with a distributed ledger technology, a token, a security, and has really just devolved into a cesspit of buzzwords and disinformation. Once satoshi disappeared in 2011 and left the repo in the hands of Gavin and the open source community, it left a power vacuum in the space for how to interpret the protocol, whitepaper and handle the development. Gavin Andresson brought some other developers on board from the forums and mailing lists, Shortly after Gavin gave some other developers commit access, bitcointalk was hacked and these new developers somehow deleted gavin from the github repo due to apparent concern that his account was compromised from the hack and afterwards once he validated his identity in certain accounts he was never given access again. Gavin stopped being involved with the project after that.
In the time following satoshi's departure a meme had evolved that satoshi had left because Gavin had met with the CIA to discuss bitcoin. This meme combined with the interpretation of what satoshi meant when he included the quote "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" in the genesis block, the subsequent rise and fall of silk road and darknet markets, and the general lore of the space, his cypherpunk mailing list associations had led the scene to paint/project upon him as some kind of government hating tax dodging l33t h4xor demigod.
Although in the title of the whitepaper it was described as p2p cash, bitcoin as most know it is now is marketed as a store of value. Although it was defined as the longest Proof of Work chain of digital signatures, bitcoin as most know it in actual fact has segregated witnesses (signatures) in the protocol. Although satoshi attests to how bitcoin is designed to scale to giant block sizes hosted and mined in data centers that never really hits a scaling ceiling, it is being sold as that even at 1MB size, the damage has already been done and the blocksize should be 300kB because every user needs to be able to run a full node for bitcoin to validate their own transactions with the lowest hardware and bandwidth requirements possible. A high vertice count with everyone running a (non-mining) full node is said to protect the network against malicious actions by the big bad government while graph theory states that it is the degree of inter connectivity of the vertcies (edge number) that confers security of the network against sybil attacks as it brings the number of hops down.
This decoupling from the original vision has led to development and scaling of bitcoin stalling for many years which led to the proliferation of many alt coins rising up to claim they possess superior attributes to bitcoin or can work in conjunction with bitcoin in a gold and silver type relationship, or serve a different use case to bitcoin. The debate between the groups that represented the opposing roadmaps reached a climax with bitcoin itself forking into two now separate blockchains with the minority chain being declared the imposter by social media claiming hashpower and the market had chosen despite their chain changing on the protocol level to implement segregated witnesses and reject the block size increase. These two now separate chains both forked again to birth bitcoin gold and diamond on the segwit chain and bitcoin cash and bitcoin sv on the non segwit chain. At the non segwit chain fork, bitcoin cash implemented checkpointing at the protocol level whereas bitcoin sv maintained the original nakamoto consensus and sought to scale greater than the 32MB blocksize limit BCH maintained with 64MB blocks.
Following these forking events both BTC (segwit) and BCH (checkpoints) also implemented Schnorr signatures which was marketed as economising the size of a typical bitcoin transaction though in actual fact it can be used to obfuscate signatures and allow for the mixing of coins to mask the chain of digital signatures and essentially "anonymously" launder money. The BSV chain (now Stewarded by Dr Craig Wright) was then declared the loser of that hash war by people heralding the power of the market and the miners to democratize money. The problem with such a claim though is just like current polical democracy, this apparent democratisation of money was just as susceptible to the influence of those who control the cryptocurrency media and just like in politics, there is a cabal like group that exerts a disproportionate influence over the narrative and appears to serve the interests of those in on the racket rather than those it is allegedly informing.
The main forums for discussion of cryptocurrency originally were bitcoin.org, bitcointalk.org and /Bitcoin with all three of them for some time sharing the same moderator theymos. Coindesk and the bitcoinmagazine (started by ethereum devs) were some early sources, talking heads like andreas antonopolos (andreasma), peter todd (petertodd) and greg maxwell (nullc) being propped up as sources of knowledge on what is the best course of action for scaling and endorsing solutions like small blocks, second layer solutions and segwit as a necessarry bitcoin improvement protocol (BIP) while people like Roger Ver (memory dealers) and Dr Craig Wright (craig_s_wright) endorsing a block size increase. Because the core developers had chosen to scale with small blocks and lots of nodes on the network were signalling in support of Segwit any discussion of a big block alternative was considered discussion of an alt coin and deleted and eventually users banned from /bitcoin. Out of that incident /btc emerged as an apparently censorship free forum for the discussion of all scaling plans for bitcoin but was ultimately a partisan sub populated with dejected big blockers. After the BCH fork, discussion for bitcoin sv exists on a few subs /bsv (modded by BCHers), /bitcoinsv (moderated by the lead technician at nChain (Craig Wright's company) and /bitcoincashsv where many users have been banned from both /bitcoin and /btc.
Now this so far is just kind of a synposis of the history of bitcoin covering all three of the main contenders for the legitimate claimant of the name but the part 2 will look more at what kind of drastically different societies would be built upon the different versions of the protocol and what may seem like their subtle differences and which one is likely to succeed.

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners
Thank you for inviting Horizen to the GPU mining AMA!
ZEN had a great run of GPU mining that lasted well over a year, and brought lots of value to the early Zclassic miners. It is mined using Equihash protocol, and there have been ASIC miners available for the algorithm since about June of 2018. GPU mining is not really profitable for Horizen at this point in time.
We’ve got a lot of miners in the Horizen community, and many GPU miners also buy ASIC miners. Happy to talk about algorithm changes, security, and any other aspect of mining in the questions below. There are also links to the Horizen website, blog post, etc. below.
So, if I’m not here to ask you to mine, hold, and love ZEN, what can I offer? Notes on some of the lessons I’ve learned about maximizing mining profitability. An update on Horizen - there is life after moving on from GPU mining. As well as answering your questions during the next 7 days.
_____________________________________________________________________________________________________

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners

Author: Rolf Versluis - co-founder of Horizen

In GPU mining, just like in many of the activities involved with Bitcoin and cryptocurrencies, there is both a cycle and a progression. The Bitcoin price cycle is fairly steady, and by creating a personal handbook of actions to take during the cycle, GPU miners can maximize their profitability.
Maximizing profitability isn't the only aspect of GPU mining that is important, of course, but it is helpful to be able to invest in new hardware, and be able to have enough time to spend on building and maintaining the GPU miners. If it was a constant process that also involved losing money, then it wouldn't be as much fun.

Technology Progression

For a given mining algorithm, there is definitely a technology progression. We can look back on the technology that was used to mine Bitcoin and see how it first started off as Central Processing Unit (CPU) mining, then it moved to Graphical Processing Unit (GPU) mining, then Field Programmable Gate Array (FPGA), and then Application Specific Integrated Circuit (ASIC).
Throughout this evolution we have witnessed a variety of unsavory business practices that unfortunately still happen on occasion, like ASIC Miner manufacturers taking pre-orders 6 months in advance, GPU manufacturers creating commercial cards for large farms that are difficult for retail customers to secure and ASIC Miner manufacturers mining on gear for months before making it available for sale.
When a new crypto-currency is created, in many cases a new mining algorithm is created also. This is important, because if an existing algorithm was used, the coin would be open to a 51% attack from day one, and may not even be able to build a valid blockchain.
Because there's such a focus on profitable software, developers for GPU mining applications are usually able to write a mining application fairly rapidly, then iterate it to the limit of current GPU technology. If it looks like a promising new cryptocurrency, FPGA stream developers and ASIC Hardware Developers start working on their designs at the same time.
The people who create the hashing algorithms run by the miners are usually not very familiar with the design capabilities of Hardware manufacturers. Building application-specific semiconductors is an industry that's almost 60 years old now, and FPGA’s have been around for almost 35 years. This is an industry that has very experienced engineers using advanced design and modeling tools.
Promising cryptocurrencies are usually ones that are deploying new technology, or going after a big market, and who have at least a team of talented software developers. In the best case, the project has a full-stack business team involving development, project management, systems administration, marketing, sales, and leadership. This is the type of project that attracts early investment from the market, which will drive the price of the coin up significantly in the first year.
For any cryptocurrency that's a worthwhile investment of time, money, and electricity for the hashing, there will be a ASIC miners developed for it. Instead of fighting this technology progression, GPU miners may be better off recognizing it as inevitable, and taking advantage of the cryptocurrency cycle to maximize GPU mining profitability instead.

Cryptocurrency Price Cycle

For quality crypto projects, in addition to the one-way technology progression of CPU -> GPU -> FPGA -> ASIC, there is an upward price progression. More importantly, there is a cryptocurrency price cycle that oscillates around an overall upgrade price progression. Plotted against time, a cycle with an upward progressions looks like a sine wave with an ever increasing average value, which is what we see so far with the Bitcoin price.

Cryptocurrency price cycle and progression for miners
This means mining promising new cryptocurrencies with GPU miners, holding them as the price rises, and being ready to sell a significant portion in the first year. Just about every cryptocurrency is going to have a sharp price rise at some point, whether through institutional investor interest or by being the target of a pump-and-dump operation. It’s especially likely in the first year, while the supply is low and there is not much trading volume or liquidity on exchanges.
Miners need to operate in the world of government money, as well as cryptocurrency. The people who run mining businesses at some point have to start selling their mining proceeds to pay the bills, and to buy new equipment as the existing equipment becomes obsolete. Working to maximize profitability means more than just mining new cryptocurrencies, it also means learning when to sell and how to manage money.

Managing Cash for Miners

The worst thing that can happen to a business is to run out of cash. When that happens, the business usually shuts down and goes into bankruptcy. Sometimes an investor comes in and picks up the pieces, but at the point the former owners become employees.
There are two sides to managing cash - one is earning it, the other is spending it, and the cryptocurrency price cycle can tell the GPU miner when it is the best time to do certain things. A market top and bottom is easy to recognize in hindsight, and harder to see when in the middle of it. Even if a miner is able to recognize the tops and bottoms, it is difficult to act when there is so much hype and positivity at the top of the cycle, and so much gloom and doom at the bottom.
A decent rule of thumb for the last few cycles appears to be that at the top and bottom of the cycle BTC is 10x as expensive compared to USD as the last cycle. Newer crypto projects tend to have bigger price swings than Bitcoin, and during the rising of the pricing cycle there is the possibility that an altcoin will have a rise to 100x its starting price.
Taking profits from selling altcoins during the rise is important, but so is maintaining a reserve. In order to catch a 100x move, it may be worth the risk to put some of the altcoin on an exchange and set a very high limit order. For the larger cryptocurrencies like Bitcoin it is important to set trailing sell stops on the way up, and to not buy back in for at least a month if a sell stop gets triggered. Being able to read price charts, see support and resistance areas for price, and knowing how to set sell orders are an important part of mining profitability.

Actions to Take During the Cycle

As the cycle starts to rise from the bottom, this is a good time to buy mining hardware - it will be inexpensive. Also to mine and buy altcoins, which are usually the first to see a price rise, and will have larger price increases than Bitcoin.
On the rise of the cycle, this is a good time to see which altcoins are doing well from a project fundamentals standpoint, and which ones look like they are undergoing accumulation from investors.
Halfway through the rise of the cycle is the time to start selling altcoins for the larger project cryptos like Bitcoin. Miners will miss some of the profit at the top of the cycle, but will not run out of cash by doing this. This is also the time to stop buying mining hardware. Don’t worry, you’ll be able to pick up that same hardware used for a fraction of the price at the next bottom.
As the price nears the top of the cycle, sell enough Bitcoin and other cryptocurrencies to meet the following projected costs:
  • Mining electricity costs for the next 12 months
  • Planned investment into new miners for the next cycle
  • Additional funds needed for things like supporting a family or buying a Lambo
  • Taxes on all the capital gains from the sale of cryptocurrencies
It may be worth selling 70-90% of crypto holdings, maintaining a reserve in case there is second upward move caused by government bankruptcies. But selling a large part of the crypto is helpful to maintaining profitability and having enough cash reserves to make it through the bottom part of the next cycle.
As the cycle has peaked and starts to decline, this is a good time to start investing in mining facilities and other infrastructure, brush up on trading skills, count your winnings, and take some vacation.
At the bottom of the cycle, it is time to start buying both used and new mining equipment. The bottom can be hard to recognize.
If you can continue to mine all the way through bottom part of the cryptocurrency pricing cycle, paying with the funds sold near the top, you will have a profitable and enjoyable cryptocurrency mining business. Any cryptocurrency you are able to hold onto will benefit from the price progression in the next higher cycle phase.

An Update on Horizen - formerly ZenCash

The team at Horizen recognizes the important part that GPU miners played in the early success of Zclassic and ZenCash, and there is always a welcoming attitude to any of ZEN miners, past and present. About 1 year after ZenCash launched, ASIC miners became available for the Equihash algorithm. Looking at a chart of mining difficulty over time shows when it was time for GPU miners to move to mining other cryptocurrencies.

Horizen Historical Block Difficulty Graph
Looking at the hashrate chart, it is straightforward to see that ASIC miners were deployed starting June 2018. It appears that there was a jump in mining hashrate in October of 2017. This may have been larger GPU farms switching over to mine Horizen, FPGA’s on the network, or early version of Equihash ASIC miners that were kept private.
The team understands the importance of the cryptocurrency price cycle as it affects the funds from the Horizen treasury and the investments that can be made. 20% of each block mined is sent to the Horizen non-profit foundation for use to improve the project. Just like miners have to manage money, the team has to decide whether to spend funds when the price is high or convert it to another form in preparation for the bottom part of the cycle.
During the rise and upper part of the last price cycle Horizen was working hard to maximize the value of the project through many different ways, including spending on research and development, project management, marketing, business development with exchanges and merchants, and working to create adoption in all the countries of the world.
During the lower half of the cycle Horizen has reduced the team to the essentials, and worked to build a base of users, relationships with investors, exchanges, and merchants, and continue to develop the higher priority software projects. Lower priority software development, going to trade shows, and paying for business partnerships like exchanges and applications have all been completely stopped.
Miners are still a very important part of the Horizen ecosystem, earning 60% of the block reward. 20% goes to node operators, with 20% to the foundation. In the summer of 2018 the consensus algorithm was modified slightly to make it much more difficult for any group of miners to perform a 51% attack on Horizen. This has so far proven effective.
The team is strong, we provide monthly updates on a YouTube live stream on the first Wednesday of each month where all questions asked during the stream are addressed, and our marketing team works to develop awareness of Horizen worldwide. New wallet software was released recently, and it is the foundation application for people to use and manage their ZEN going forward.
Horizen is a Proof of Work cryptocurrency, and there is no plan to change that by the current development team. If there is a security or centralization concern, there may be change to the algorithm, but that appears unlikely at this time, as the hidden chain mining penalty looks like it is effective in stopping 51% attacks.
During 2019 and 2020 the Horizen team plans to release many new software updates:
  • Sidechains modification to main software
  • Sidechain Software Development Kit
  • Governance and Treasury application running on a sidechain
  • Node tracking and payments running on a sidechain
  • Conversion from blockchain to a Proof of Work BlockDAG using Equihash mining algorithm
After these updates are working well, the team will work to transition Horizen over to a governance model where major decisions and the allocation of treasury funds are done through a form of democratic voting. At this point all the software developed by Horizen is expected to be open source.
When the governance is transitioned, the project should be as decentralized as possible. The goal of decentralization is to enable resilience and preventing the capture of the project by regulators, government, criminal organizations, large corporations, or a small group of individuals.
Everyone involved with Horizen can be proud of what we have accomplished together so far. Miners who were there for the early mining and growth of the project played a large part in securing the network, evangelizing to new community members, and helping to create liquidity on new exchanges. Miners are still a very important part of the project and community. Together we can look forward to achieving many new goals in the future.
