New people please read this. [upvote for visibility please]
I am seeing too many new people come and and getting confused. Litecoin wiki isn't the greatest when it comes to summing up things so I will try to do things as best as I can. I will attempt to explain from what I have learned and answer some questions. Hopefully people smarter than me will also chime in. I will keep this post updated as much as I can. Preface Litecoin is a type to electronic currency. It is just like Bitcoin but it there are differences. Difference explained here. If you are starting to mine now chances are that you have missed the Bitcoin mining train. If you really want your time and processing power to not go to waste you should mine LTC because the access to BTC from there is much easier. Mining. What is it? Let's get this straight. When making any financial commitment to this be prepared to do it with "throw away" money. Mining is all about the hashrate and is measured in KH/s (KiloHash/sec). Unlike the powerful ASICs (Application Specific Integrated Circuit) that are used to mine bitcoins using hashrates in the GH/s and even TH/s, litecoin mining has only been able to achieve at the very best MH/s. I think the highest I've seen is 130 MH/s so far. Which leads us to our next section. Mining Hardware While CPU mining is still a thing it is not as powerful as GPU mining. Your laptop might be able to get 1 a month. However, I encourage you to consult this list first. List of hardware comparison You will find the highest of processors can maybe pull 100 KH/s and if we put this into a litecoin mining calculator it doesn't give us much. Another reason why you don't want to mine with your CPU is pretty simple. You are going to destroy it. So this leaves us with GPUs. Over the past few months (and years) the HD 7950 has been the favourite because it drains less power and has a pretty good hashrate. But recently the introduction of the R9 290 (not the x) has changed the game a bit. People are getting 850 KH/s - 900 KH/s with that card. It's crazy. Should I mine? Honestly given the current difficulty you can make a solid rig for about $1100 with a hashrate of 1700 KH/s which would give you your investment back in about a month and a half. I am sure people out there can create something for much cheaper. Here is a good example of a setup as suggested by dystopiats PCPartPicker part list / Price breakdown by merchant / Benchmarks
Prices include shipping, taxes, and discounts when available.

Estimated Hashrate (with GPU overclocking) : 1900 KH/s Hardware Fundamentals CPU - Do you need a powerful CPU? No but make sure it is a decent one. AMD CPUs are cheap to buy right now with tons of power. Feel free to use a Sempron or Celeron depending on what Motherboard you go with. RAM - Try to get at least 4 GB so as to not run into any trouble. Memory is cheap these days. I am saying 4 GB only because of Windoze. If you are plan to run this on Linux you can even get away with less memory. HDD Any good ol 7200 RPM hard drive will do. Make sure it is appropriate. No point in buying a 1TB hard drive. Since, this is a newbie's guide I assumed most won't know how to run linux, but incase you do you can get a USB flash drive and run linux from it thus removing the need for hard drive all toghether. (thanks dystopiats) GPU - Consult the list of hardware of hardware I posted above. Make sure you consider the KH/s/W ratio. To me the 290 is the best option but you can skimp down to 7950 if you like. PSU - THIS IS BLOODY IMPORTANT. Most modern GPUs are power hungry so please make sure you are well within the limits of your power consumption. MOTHERBOARD - Ok, so a pretty popular board right now is Gigabyte GA-990FXA-UD3 and the ASRock 970 Extreme4. Some people are even going for Gigabyte GA-990FXA-UD5 and even the mighty Gigabyte GA-990FXA-UD7 because it has more PCI-E slots. 6 to be exact. However you may not need that much. With risers you can get more shoved into less. PCI-E RISERS - These are called risers. They come in x16 to x16 and x1 to x16 connections. Here is the general rule of thumb. This is very important. Always get a POWERED riser otherwise you will burn a hole in your MoBo. A powered rise as a molex connector so that additional power from PSU can be supplied. When it comes to hardware I've provided the most basic knowledge you need. Also, take a look at cryptobader's website. This is very helpful. Please visit the mining section of Litecoin Forums and the litecoinmining subreddit for more indepth info. Mining Software Now that you have assembled your hardware now you need to get into a pool. But before you do that you need a mining software. There are many different ones but the one that is most popular is cgminer. Download it and make sure you read the README. It is a very robust piece of software. Please read this if you want to know more. (thanks BalzOnYer4Head) Mining Pools Now that your hardware and software is ready. I know nothing about solo mining other than the fact that you have to be very lucky and respectable amount of hashing power to decrypt a block. So it is better to join pools. I have been pool hopping for a bit and really liked give-me-coin previously known to the community as give-me-ltc. They have a nice mobile app and 0% pool fees. This is really a personal preference. Take a look at this list and try some yourself. How do I connect to a pool? Most pools will give you a tutorial on how to but the basics are as follows:
Signup for a pool
Create a worker for your account. Usually one worker per rig (Yes people have multiple rigs) is generally a good idea.
Create a .run file. Open up notepad and type cgminer.exe -o (address_to_the_miningpool:port_number) -u (yourusername.workername) -p (your_worker_password_if_you_made_one). Then File>Save As>runcgminer.run (Make sure the drop down is set to "All Files" and .txt document.) and save in the same folder as cgminer. That's it.
Double click on runcgminer.run (or whatever you named it) and have fun mining.
Mining Profitability This game is not easy. If it was, practically everyone would be doing it. This is strictly a numbers game and there are calculations available that can help you determine your risk on your investments. 4 variables you need to consider when you are starting to mine: Hardware cost: The cost of your physical hardware to run this whole operation. Power: Measured in $/KwH is also known as the operating cost. Difficulty rate: To put it in layman's terms the increase in difficulty is inversely proportional to amount of coin you can mine. The harder the difficulty the harder it is to mine coin. Right now difficulty is rising at about 18% per 3 days. This can and will change since all you miners are soon going to jump on the band wagon. Your sanity: I am not going to tell you to keep calm and chive on because quiet frankly that is stupid. What I will tell you not to get too carried away. You will pull you hair out. Seriously. Next thing you will need is a simple tool. A mining profitability calculator. I have two favourite ones. coinwarz I like this one cause it is simple. The fields are self explanatory. Try it. bitcoinwisdom I like this one because it is a more real life scenario calculator and more complicated one (not really). It also takes increasing difficulty into account. Please note: This is the absolute basic info you need. If you have more questions feel free to ask and or google it! More Below.
MAD Doge - Such Problems, Much Solutions, Year of DOGE. (March 30th, 2014)
MAD Doge – 3/30/2014 The epic battle in price PANIC! PANIC? Well yes, panic if you want, it’s apocalypse time.
ASICs - What's wrong with efficiency?
ASICs concentrate the mining power to connected and individuals who can either build the mining devices or fabricate the chips. Since they are application specific, the cost and availability is not held up by alternative uses.
ASICs introduce incredible hashing power which can allow 51% attacks for a cost-effective price. Additionally, Multipool effects can be multiplied as well as become easier with ASIC / GPU combined mining.
ASICs are a losing game unless you have the ability to get in on unreleased designs. Buying an ASIC without access to these designs will always leave you at a generation behind the current standard. (Look at Block Erupters - The people who purchased them for $100/piece are doomed to sell them for less as mining can never compensate their losses)
Cryptocurrency is considered a property for taxable purposes, this can cause problems since there are a variety of ways this can be considered, referencing transactions for new transactions will cause a variety of exchange rates to be concentrated at one transaction and the change in value overall has to be calculated for it to be reported on your W-2 tax form (For the USA MAD Doge's)
Cryptocurrency exchanges might accept this and fight to keep this since you will be required to use a cryptocurrency exchange or similar group to track your transactions for taxable purposes. This ADDS additional transaction fees that go directly against one of the core goals of BitCoin...minimal transaction fees - VIDEO LINK (Notice anything that has changed since the generation of this video?.
The need for DogeCoin to have a higher value
DogeCoin needs a higher value as time goes on in order to keep people mining and to avoid the profitability of a 51% attack. Unfortunately, the last halving has left us at only an increase from some of the lowest numbers to around 120 satoshi. Even though this is above double the last average low (58 satoshi), this is actually lower in tradeable value as DogeCoin has dropped with BitCoin to less than the comfortable average of $0.001/DOGE - Side Note: If you're reading this, reply to this post with a joke, I'll tip a bunch.
DogeCoin Value can increase one of two ways and a variety in between: A jump in mining cost and overal hashrate (all else held constant) or a jump in DogeCoin demand. Some might think that ASIC's are a great solution since the hashrate will jump through the roof, however this is foolish. There will not be a cost rise overall since the price to mine will drop as these new asics are rolled out. The difficulty will rise and mining will be backed by a smaller group that mine at a lower cost, thus the new miners will be willing to sell for less.
What am I doing? How am I invested in a solution? (WOW SUCH LONG READ)
I mine via GPU's, my current hashrate is 700-900kh/s. I am running 7790 graphics cards and have recently switched to two 270's which are at 420kh/s average. They're not getting much return, but at least I'm helping keep the system from being 51%'d
I invest in new cryptocurrencies, even if they lose me money (I have lost $50 in new cryptocurrencies) since it is important to buy in to new cryptocurrencies in order to keep their value up so that the development keeps improving. I invested in KGW (Kimoto's Gravity Well) based currencies and Scrypt-N (which I refuse to mine...yet) proof-of-work currencies as well as ones that offer unique improvements to everyday cryptocurrency problems.
Pushing for a solution to ASICs in the order of finding a new way to do Proof-of-Work that is highly efficient on GPU's and CPU's so that anyone can mine equally and profitably (If they are willing to do so).
What's going to happen?
Prices are going to drop until we get a permanent solution or higher demand for DogeCoin. People right now have other larger problems to worry about and will focus on them primarily. Watch out for the price drops near USA Tax Day (April 15th) and possible April Fools price fluctuations if people take fake stories seriously.
Watch out for DogeCar, the price is definitely going to rise, but it's going to be a hard sell since we're basically trying to sell a precious metal now (according to USA's IRS), if you think that's easy, google search gold informercials since gold is also a property.
Prepare for a fork, if new ASICs come on the market and dwarf the current hashrate, a 51% attack could cause us to fork, similar to how AuroraCoin forked. This could also cause Multipool-type shenanigans again.
It's going to be a rough ride, but there are upsides, Cryptsy has started on USD/DOGE exchanges.
I have looked over google for some help but im obviously not looking in the correct places because I did not see what i need. Hopefully someone here can point me in the right direction. Here is whats going on. I started off with 1 asic block erupter (ASICMiner Block Erupter USB 330MH/s Sapphire Miner) and everything was going fine. i added another one to the setup and everything was still going fine. (this is all being done on USB ports that are on the back of my PC, no USB hub, yet) I then aquired an antminer (BITMAIN ANTMINER U2 2Gh/s USB Bitcoin ASIC Miner. Overclockable) and plugged it into my PC as well. I am using BFGminer 3.10.0 currently and everything was running fine. all 3 miners were mining. I went ahead and ordered a usb hub because i figured if i was going to keep adding miners that my computer would not be a good place to put them all. well a day before the hub got here, i noticed that one of the miners (the saphire one) was not mining. i looked at my device manager and only saw 2 of them. so i rebooted, messed around with some different ports but nothing made that one work. i figured it was broken for whatever reason and assumed it was because it wasnt suppose to be on my mother board. thing is, it works on another PC. so i waited for the hub to come in to see if it would work on there but it still does not. Im thinking its a driver issue since its not showing up on this computer but it will on another. Any idea or suggestion on how to get my current PC (windows 8.0) to run it? Should i try a different version of bfgminer, or maybe cgminer? im fairly new to all this so i dont really know where to go with it.

SOLD Both rigs runs Windows and comes with the installation disc (Dell branded), but I was running a live Debian-based OS from a USB drive that will be included (4gb). It supports litecoin and bitcoin, and even the USB ASIC block erupters. It has remote monitoring support, which is mainly why I used it. Will accept litecoin, bitcoin, Paypal, Dwolla, or Wells Fargo transfers. I would rather not ship outside the USA or part out. If no one is interested here, I will likely just list them on eBay.
[SG] I Am Accepting DOGE as Payment for Custom GPU Mining Rigs for Local Pickup in Chicago, IL USA
I have two custom rigs / mining kits IN HAND and I am willing to sell. I will accept Bitcoin or Dogecoin for payment of course, or USD if you prefer I guess =) Topaz - $850 / 1.7 BTC / 850k DOGE - 2x Sapphire R9 270 GPUs - Motherboard, CPU+fan, 3GB DDR2 RAM - 1x USB Powered PCI-E 1x to 16x Riser - 1x 40GB SATA Hard Drive - 750W PSU - Open air black metal frame - 810 kh/s Scrypt Mining on cgminer 3.7.2 Jet - $950 / 1.9 BTC / 950k DOGE - 2x Sapphire R9 270x GPU - Motherboard, CPU+fan, 8GB DDR3 RAM - 1x USB Powered PCI-E 1x to 16x Riser - 1x 40 GB SATA Hard Drive - 1000W PSU - Open air black metal frame - 880 kh/s Scrypt Mining on cgminer Sorry but prices in BTC/DOGE are subject to change, I have to pay USD for all of the components here so I have to adjust for the exchange rate. Prices quoted here reflect the current exchange rates and will have to be recalculated if there is significant gain or loss of value on the markets. Both rigs are mining away at the moment with cgminer 3.7.2, so if you want them they are basically plug-and-play, just need to be configured to point at your pools (which I can show you how to do if you are a newbie). Windows 7 is the 'trial version' so it will ask you for a validation code but it will run just fine without it. I am also willing to build and deliver fully working CUSTOM MINING RIGS at various hashing powers - 800, 900, 1200, 1500, and 2200 - for around $1.25 per kh/s (with payment up front). Professionally I am a career educator, so I am very patient and willing to sit down with you if you are unfamiliar with crypto and explain how everything works. I will make sure that the miner I sell is configured right and ready-to-hash, and I will explain to you how to use it and how to keep it running right. I have mined scrypt coins on several different types of cards using both Linux and Windows OS, I have mined BTC using ASIC hardware, I have managed exchange accounts, qt-clients, and a futures account on ICBIT. So basically I have some knowledge and expertise I am willing to share with anyone who is interested and willing to invest some money with me for hardware. I think that GPU rigs are still a very good investment in crypto for two reasons. At the moment the scrypt coin economy is pretty stable. 1,000 kh/s will get you the equivalent of 0.010 - 0.015 BTC/day depending on which scrypt coin you choose. There are several coins that give at least this good of a return, which is great on its own. But then add the fact that GPUs can be resold for a very good portion of the original value, and that a mining rig can be re-purposed as a workstation or gaming rig. Personally I think I can offer a really good value, and if my apartment were rated to deliver more electricity without overloading my circuits, I would be building and mining off of more cards myself. I am also willing to buy/sell limited amounts of cryptocurrency in person - up to $1,000 USD. I have well established accounts on major exchanges so if you are looking to buy or sell without all that hassle, I can help you out.
Bitcoin mining made really easy/BFGminer quick start guide
There is 2 parts to this If i am missing somthing of if you want to add to this then please tell ms so i can make the changes. All is one and one is all. Infomation wants to be free, so dont be a dick help me make this better for all. Oh one more thing before we start I don't give a rats ass about up votes or down votes or square votes for this matter, I made this to help anyone who is stuck, if you don't like it then scram!(Its not like im forcing you to read this)...Or i am i ... So if you new or experienced bitcoin miner you should know that shit ain't free. The reason for this is the fact that electric isn't free.(Oh the fun days we would have if it was) When mining there is always going to be a cost, like how to pay for the Hardware, and the power and the maintenance and something that everyone forgets, The time it can take to set up the hardware and the scripts to miner. I chose to do a side project on this and got my own Asic miner USB Block eruptor that mines at 336mhs. It took me about 6 hours to write a working batch file. So show i wanted to show it to you all because it is a pain in the ass. BFGMINER PART So If your using "ASICMiner Block Erupter USB 333-336MH/s Sapphire Miner" You have found the right page You will need install the drivers here is the link = These drivers may be downloaded from: http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx So this is what i use BFGMINER.exe Verson 3.2.1 So i made a batch file With this in it.(If you need help making this then please tell me.I don't mind helping.) C:\Users\Admin\Desktop\bfgminer-3.2.1-win64\bfgminer-3.2.1-win64\bfgminer.exe -o stratum+tcp://uk1.ghash.io:3333 -u YOURNAMEHER.worker1 -p YOURPASSWORD --disable-gpu -S all -o stratum+tcp://uk1.ghash.io:3333 This is my mining pool -S all will find all divices -disable-gpu because i don't want it to mine on my GPU. Make this the location of you BFG miner C:\Users\Admin\Desktop\bfgminer-3.2.1-win64\bfgminer-3.2.1-win64\bfgminer.exe -u YOURNAMEHER.worker1 This is your username and workername. -p YOURPASSWORD This is your password So from all of this it worked i have basically pieced together everything that i found to make the batch file that will start mining Woot Woot Empty Space Bitcoin mining made really easy PART How to start * Sign up at Cex.io if you don't already have an account. Then you can buy GH/S of mining speed. From Ebay Just type in Cex.io in ebay and you will find it all. READ ALL THE POSTS CAREFULLY. People can and will be dicks and try to trick you like saying 10000 kh/s of mining power, People that is 10 mb/s. Aka nothing When you get a voucher code You will immediately start mining Bitcoins. You don't have to worry about setting anything up, electricity, power outages, or bad hardware. The Benefits *No technical knowledge required. *No hardware to maintain. *No software to configure. *No electricity cost. *If there server gose down they will bous your speed of the miner to make up for the down time(that is really cool, i only had this happen once......The went down for about 13 hours and i normale was mining at 2gbs but the bumped me up to 6 gbs for a few hours to make up for the down time... *You can buy gh/s witht the bitcoins you mine. *Supports Merged mining.This means it Mines Bitcoin, Namecoin, Devcoin, and IXcoin at the same time! The Disadvantages *you cant buy gh/z with money, they will only accept bitcoins *If you like to physical hold the miner then this isnt for you.(Hey i do both so its the best of both worlds)
It uses an Application Specific Integrated Chip known as ASIC, the first of its kind for Bitcoin Mining. BITCOIN USB ASIC Miner Block Erupter available now! This is an ASICMINER USB BLOCK Erupter (Sapphire Batch). This USB devices mines Bitcoin at a confirmed ~335 MHash while using only USB spec power (0.5 Watt). This unit is from ASICMINER. Our journey begins with the ASICMiner Block Erupter Sapphire miner. Although this wasn’t the first ever Bitcoin ASIC introduced it was the first one that wasn’t nearly impossible to get your hands on. This miner was powered by the BE100 chipset (ASICMiner’s first generation 1 chip). The mining speed of the miner was 330 MH/s. ASICMiner Block Erupter USB 330MH/s Sapphire Miner. The Sapphire Block Erupters were the first Bitcoin USB miners. They have 330 MH/s of hash power which would net you less than $0.01 per month. It may be a good choice just to see how mining works, but like with most USB miners: do not expect to turn a profit. GekkoScience Compac USB Stick ASICMiner Block Erupted USB 330MH/s Sapphire Miner For a good learning experience, this may be your best option, as the Sapphire Block Erupters were among the first USB Bitcoin miners. However, with its hash power of 330 MH/s, it’s not something you’ll want to use if you’re in it to make a profit. Block Erupter USBs were first announced by ASIC Miner on BitcoinTalk.org in 2013. They were a portable, pocket sized yet relatively powerful bitcoin usb miners, and were suggested as «a perfect gift for getting people knowing about Bitcoin and Bitcoin mining».
