Bitcoin Mining Profitability: How Long Does it Take to Mine One Bitcoin in 2019?

When it comes to Bitcoin (BTC) mining, the major questions on people’s minds are “how profitable is Bitcoin mining” and “how long would it take to mine one Bitcoin?” To answer these questions, we need to take an in-depth look at the current state of the Bitcoin mining industry — and how it has changed — over the last several years.
Bitcoin mining is, essentially, the process of participating in Bitcoin’s underlying security mechanism — known as proof-of-work — to help secure the Bitcoin blockchain. In return, participants receive compensation in bitcoins (BTC).
When you participate in Bitcoin mining, you are essentially searching for blocks by crunching complex cryptographic challenges using your mining hardware. Once a block is discovered, new transactions are recorded and verified within the block and the block discoverer receives the block rewards — currently set at 12.5 BTC — as well as the transactions fees for the transactions included within the block.
Once the maximum supply of 21 million Bitcoins has been mined, no further Bitcoins will ever come into existence. This property makes Bitcoin deflationary, something which many argue will inevitably increase the value of each Bitcoin unit as it becomes more scarce due to increased global adoption.
The limited supply of Bitcoin is also one of the reasons why Bitcoin mining has become so popular. In previous years, Bitcoin mining proved to be a lucrative investment option — netting miners with several fold returns on their investment with relatively little effort.

Mining Hardware
The mining hardware you choose will mostly depend on your circumstances — in terms of budget, location and electricity costs. Since the amount of hashing power you can dedicate to the mining process is directly correlated with how much Bitcoin you will mine per day, it is wise to ensure your hardware is still competitive in 2019.
Bitcoin uses SHA256 as its mining algorithm. Because of this, only hardware compatible with this algorithm can be used to mine Bitcoin. Although it is technically possible to mine Bitcoin on your current computer hardware — using your CPU or GPU — this will almost certainly not generate a positive return on your investment and you may end up damaging your device.
The most cost-effective way to mine Bitcoin in 2019 is using application-specific integrated circuit (ASIC) mining hardware. These are specially-designed machines that offer much higher performance per watt than typical computers and have been an absolutely essential purchase for anybody looking to get into Bitcoin mining since the first Avalon ASICs were shipped in 2013.
When it comes to selecting Bitcoin mining hardware, there are several main parameters to consider — though the importance of each of these may vary based on personal circumstances and budget.
Performance per Watt
When it comes to Bitcoin mining, performance per watt is a measure of how many gigahashes per watt a machine is capable of and is, hence, a simple measure of its efficiency. Since electricity costs are likely to be one of the largest expenses when mining Bitcoin, it is usually a good idea to ensure that you are getting good performance per watt out of your hardware.
Ideally, your mining hardware would be highly efficient, allowing it to mine Bitcoin with lower energy requirements — though this will need to be balanced with acquisition costs, as often the most efficient hardware is also the most expensive. This means it may take longer to see a return on investment.
In countries with cheap electricity, performance per watt is often less of a concern than acquisition costs and price-performance ratio. In most countries, operating outdated mining hardware is typically cost prohibitive, as energy costs outweigh the income generated by the mining equipment.
However, this may not be the case for those operating in countries with extremely cheap electricity — such as Kuwait and Venezuela — as even older equipment can still be profitable. Similarly, miners with a free energy surplus, such as from wind or solar electric generators, can benefit from the minimal gains offered by still running outdated hardware.
Longevity
The lifetime of mining hardware also plays a critical role in determining how profitable your mining venture will be. It’s always a good idea to do whatever possible to ensure it runs as smoothly as possible.
Since mining equipment tends to run at a full (or almost full) load for extended periods, they also tend to break down and fail more frequently than most electronics — which can seriously damage your profitability. Equipment failure is even more common when purchasing second-hand equipment. Since warranty claims are often challenging, it can often take a long time to receive a warranty replacement.
Price-Performance Ratio
In many cases, one of the major criteria used to select mining hardware is the price-performance ratio — a measure of how much performance a machine outputs per unit price. In the case of cryptocurrency mining hardware, this is commonly expressed as gigahashes per dollar or GH/$.
Under ideal circumstances, the mining hardware would have a high price-performance ratio, ensuring you get a lot of bang for your buck. However, this must also be considered in combination with the acquisition costs and the expected lifetime of the machine — since the absolute most powerful machines are not always the cheapest or the most energy efficient.
Acquisition Costs
Acquisition costs are almost always the biggest barrier to entry for most Bitcoin miners since most top-end mining hardware costs several thousand dollars. This problem is further compounded by the fact that many hardware manufacturers offer discounts for bulk purchases, allowing those with deeper pockets to achieve a better price-performance ratio.
Acquisition costs include all the costs involved in purchasing any mining equipment, including hardware costs, shipping costs, import duties, and any further costs. For example, many ASIC miners do not include a power supply — which can be another considerable expense, since the 1,000W+ power supplies usually required tend to cost several hundred dollars alone.
Ensuring your equipment runs smoothly can also add in additional costs, such as cooling and maintenance expenses. In addition, some miners may want to invest in uninterruptible power supplies to ensure their hardware keeps running — even if the power fails temporarily.
asic mining
Current Generation Hardware
One of the most recent additions to the Bitcoin mining hardware market is the Ebang Ebit E11++, which was released in October 2018. Using a 10nm fabrication process for its processors, the Ebit E11++ is able to achieve one of the highest hash rates on the market at 44TH/s.
In terms of efficiency, the Ebang Ebit E11++ is arguably the best on the market, offering 44TH/s of hash rate while drawing just 1,980W of power, offering 22.2GH/W performance. However, as of writing, the Ebang Ebit E11++ is out of stock until March 31, 2019 — while its price of $2,024 (excluding shipping) may make it prohibitively expensive for those first getting involved with Bitcoin mining.
Another popular choice is the ASICminer 8 Nano, a machine released in October 2018 that offers 44TH/s for $3,900 excluding shipping. The ASICminer 8 Nano draws 2,100W of power, giving it an efficiency of almost 21GH/W — slightly lower than the Ebit E11++ while costing almost double the price. However, unlike the E11++, the 8 Nano is actually in stock and available to purchase.
ASICminer also offers the 8 Nano Pro, a machine launched in mid-2018 that offers 80 TH/s of hash rate for $9,500 (excluding shipping). However, unlike the Ebit E11++ and 8 Nano, the minimum order quantity for the 8 Nano Pro is curiously set at five, meaning you will need to lay out a minimum of $47,500 in order to actually get your hands on one (or five).
While the 8 Nano Pro doesn’t offer the same performance per watt as the Ebit E11+ or AICMiner 8 Nano, it is one of the quieter miners on this list, making it more suitable for a home or office environment. That being said, the ASICminer 8 Nano Pro is easily the most expensive miner per TH on this list — costing a whopping $118.75/TH, compared to the $46/TH offered by the E11++ and $88.64 offered by the 8 Nano.
The latest hardware on this list is the Innosilicon T3 43T, which is currently available for pre-order at $2,279, and estimated to ship in March 2019. Offering 43TH/s of performance at 2,100W, the T3 43T comes in at an efficiency of 20.4GH/W, which is around 10 percent less energy efficient than the Ebit E11++.
The T3 43T also has a minimum order quantity of three units, making the minimum acquisition cost $6837 + shipping for preorders. All in all, the T3 43T is more costly and less efficient than the E11++ but may arrive slightly earlier since Ebang will not ship the E11++ units until at least end March 29, 2019.
Finally, this list would not be complete without including Bitmain’s latest offering, the Antminer S15-28TH/s, which — as its name suggests — offers 28TH/s of hash power while drawing just under 1600W at the wall. The Antminer S15 is one of the only SHA256 miners to use 7nm processors, making it somewhat smaller than some of the other devices on this list.
Like most pieces of top-end Bitcoin mining hardware, the Antminer S15 27TH/s model is currently sold out, with current orders not shipping until mid-February 2019. However, the S15 is offered at a significantly lower price than many of its competitors at just $1020 (excluding shipping), with no minimum quantity restriction. At these rates, the Antminer comes in at just $37.78/TH — though its energy efficiency is a much less impressive 17.5GH/W.

How To Select a Good Mining Pool
Mining pools are platforms that allow miners to pool their resources together to achieve a higher collective hash rate — which, in turn, allows the collective to mine more blocks than they would be able to achieve alone.
Typically, these mining pools will distribute block rewards to contributing miners based on the proportion of the hash rate they supply. If a pool contributing a total of 20 TH/s of hash rate successfully mines the next block, a user responsible for 10 percent of this hash rate will receive 10 percent of the 12.5 BTC reward.
Pools essentially allow smaller miners to compete with large private mining organizations by ensuring that the collective hash rate is high enough to successfully mine blocks on regular basis. Without operating through a mining pool, many miners would be unlikely to discover any blocks at all — due to only contributing a tiny fraction of the overall Bitcoin hash rate.
While it is quite possible to be successful mining without a pool, this typically requires an extremely large mining operation and is usually not recommended — unless you have enough hash rate to mine blocks on a regular basis.
Although it is technically possible to discover blocks mining solo and keep the entire 12.5 BTC reward for yourself, the odds of this actually occurring are practically zero — making pool collaboration practically the only way to compete in 2019 and beyond.
Selecting the best pool for you can be a challenging job since the vast majority of pools are quite similar and offer similar features and comparable fees. Because of this, we have broken down the qualities you should be looking for in a new pool into four categories; reputation, hash rate, pool fees, and usability/features:
Reputation
The reputation of a pool is one of the most important factors in selecting the pool that is best for you. Well-reputed pools will tend to be much larger than newer or less well-established pools since few pools with a poor reputation can stand the test of time.
Well-reputed pools also tend to be more transparent about their operation, many of which provide tools to ensure that each user is getting the correct reward based on the hash rate contributed. By using only pools with a great reputation, you also ensure your hash rate is not being used for nefarious purposes — such as powering a 51 percent attack.
When comparing a list of pools that appear suitable for you, it is a wise move to read their user reviews before making your choice — ensuring you don’t end up mining at a pool that steals your hard-fought earnings.
Hash Rate
When it comes to mining Bitcoin, the probability of discovering the next block is directly related to the amount of hashing power you contribute to the network. Because of this, one of the major features you should be considering when selecting your pool is its total hash rate — which is often closely related to the proportion of new blocks mined by the pool
Since the total hash rate of a pool is directly related to how quickly it discovers new blocks, this means the largest pools tend to discover a relative majority of blocks — leading to more regular rewards. However, the very largest pools also tend the have higher fees but often make up for this with sheer success and additional features.
Sometimes, some of the largest pools have a minimum hash rate requirement ù leaving some of the smaller miners left out of the loop. Although smaller pools typically have more relaxed requirements with reduced performance thresholds, these pools may be only slightly more profitable than mining solo.
Pool Fees
When choosing a suitable pool, typically one of the major considerations is its fees. Typically, most pools will charge a small fee that is deducted from your earnings and is usually around 1-2 percent — but sometimes slightly lower or higher.
There are also pools that offer 0 percent fees. However, these are often much smaller than the major pools and tend to make their money in a different way — such as through monthly subscriptions or donations.
Ideally, you will choose the pool that offers the best balance of fees to other features. Usually, the pool with the absolute lowest fees is not the best choice. Additionally, pools with the lowest fees often have the highest withdrawal minimums — making pool hopping uneconomical for most.
Usability and Features
When first starting out with Bitcoin mining, learning how to set up a pool and navigating through the settings can be a challenge. Because of this, several pools target their services to newer users by offering a simple to navigate user interface and providing detailed learning resources and prompt customer support.
However, for more experienced miners, simple pools don’t tend to offer a variety of features needed to maximize profitability. For example, although many mining pools focus their entire hash rate towards mining a single cryptocurrency, some are large enough to offer additional options — allowing users to mine other SHA256 coins such as Bitcoin Cash (BCH) or Fantom if they choose.
These pools are technically more challenging to use and mostly designed for those familiar with mining, happy to hop from coin to coin mining whichever is most profitable at the time. There are even some exchanges that automatically direct their combined hash rate at the most profitable cryptocurrency — taking the guesswork out of the equation.

Best Mining Pools for 2019
The Bitcoin mining pool industry has a large number of players, but the vast majority of the Bitcoin hash rate is concentrated within just a few pools. Currently, there are dozens of suitable pools to choose from — but we have selected just a few of the best to help get you started on your journey.
Slushpool was the first Bitcoin mining pool released, being launched way back in 2010 under the name “Bitcoin Pooled Mining Server.” Since then, Slushpool has grown into one of the most popular pools around — currently accounting for just under 10 percent of the total Bitcoin hash rate.
Although Slushpool isn’t one of the very largest pools, it does offer a newbie-friendly interface alongside more advanced features for those that need them. The pool has moderately high fees of 2 percent but offers servers in several countries — including the U.S., Europe, China, and Japan — giving it a good balance of fees to features.
BTC.com is another potential candidate for your pool and currently stands as the largest public Bitcoin mining pool. It is responsible for mining around 17 percent of new blocks. Being the largest public mining pool provides users with a sense of security, ensuring blocks are mined regularly and a stable income is made.

BTC.com is owned by Bitmain, a company that manufacturers mining hardware, and charges a 1.5 percent fees — placing it squarely in the middle-tier in terms of fees. Unlike other platforms, BTC.com uses its own payment structure known as FPPS (Full Pay Per Share), which means miners also receive a share of the transaction fees included within mined blocks — making it slightly more profitable than standard payment per share (PPS) pools.
Another great option is Antpool, a mining pool that supports mining services for 10 different cryptocurrencies, including Bitcoin, Litecoin (LTC) and Ethereum (ETH). AntPool frequently trades places with BTC.com as the largest Bitcoin mining pool. However, as of this writing, it occupies the title of the third-largest public mining pool.
What sets Antpool apart from other pools is the ability to choose your own fee system — including PPS, PPS+, and PPLNS. If you choose PPLNS, using Antpool is free but you will not receive any transaction fees from any blocks mined. Antpool also offers regular payouts and has a low minimum payout of just 0.001 BTC, making it suitable for smaller miners.
Last on the list of the best Bitcoin mining pools in 2019 is the Bitcoin.com mining pool. Although this is one of the smaller pools available, the Bitcoin.com pool has some redeeming features that make it worth a look. It offers mining contracts, allowing you to test out Bitcoin mining before investing in mining equipment of your own. According to Bitcoin.com, they are the highest paying Pay Per Share (PPS) pool in the world, offering up to 98 percent block rewards as well as automatic switching between BTC and BCH mining to optimize profitability.

Electricity Costs
While your mining hardware is most important when it comes to how much BTC you can earn when mining, your electricity costs are usually the largest additional expense. With electricity costs often varying dramatically between countries, ensuring you are on the best cost-per-KWh plan available will help to keep costs down when mining.
Most commonly, large mining operations will be set up in countries where electricity costs are the lowest — such as Iceland, India, and Ukraine. Since China has one of the lowest energy costs in the world, it was previously the epicenter of Bitcoin mining. However, since the government began cracking down on cryptocurrencies, it has largely fallen out of favor with miners.
Technically, Venezuela is one of the cheapest countries in the world in terms of electricity, with the government heavily subsidizing these energy costs — while Bitcoin offers an escape from the hyperinflation suffered by the Venezuelan bolivar. Despite this, importing mining hardware into the country is a costly endeavor, making it impractical for many people.
Finding ways to lower your electricity costs is one of the best ways to improve your mining profitability. This can include investing in renewable energy sources such as solar, geothermal, or wind — which can yield increased profitability over the long term.

Mining Sigil with Nvidia. How and why.

So I'm currently mining Sigil with a single 1080 Ti. It's a very young coin that works as a hybrid PoS/PoW. The official Sigil pool is a 0% fee and has most of the nethash. I'm using the HSR Miner Neoscrypt software which gives me about 1900KH/s on my card with +100 core +800 memory. This is netting me 30-40 coins/day on the low end with a 2GH/s and 75+ when the nethash is smaller around 700MH/s. With the current value of the coin sitting at roughly 3000 Satoshi's they're worth around $.35 each as of this writing. That's about $14/day for a single card. The only exchange it's currently listed on is coinhouse.eu, but stocks.exchange should have them listed very shortly. All in all it's not to bad and gives a good incentive to mine Sigil.
(Insert Billy Mays, but wait there's more! here)
Sigil isn't just a coin, there's more to it than that. The devs have a planned crowdfunding site called Sigil Go that the currency revolves around. The idea behind the site is crowdfunding for the rest of the world and for the good of the world. Crowdfunding clean water and energy for the developing world, disaster relief and other awesome things could be as simple as backing some self-stirring yogurt cup on Kickstarter.
It's worth doing it for the monetary value alone I think, but I'm hopeful that it could become something great for other reasons.
Disclaimer: I have quite a few Sigil coins but am in no way a affiliated with the team running the project. I'm just hoping it grows and becomes something very cool.

First Experiment in Mining, even lowest hopes get disappointed.

Hi guys,
I wanted to know if Mining can be a valid option to make money (like so many others). But instead of spending thousands of bucks for my first disappointment I simply bought a 35€ 2GH/s Antminer U2. After about 24 hours of mining with the btcguild pool I've received about ~1300 satoshis which calculates to not even 0.01€ using google.com for the bitcoin-euro price.
If I ask for the euro price of 0.00001323 (current earnings) *365 (days per year) * 24 (number of years) btc in eur then I get about my 35€. So in the current price and Difficulty situation I need about 24 years of 24/7 mining to cover my expenses, considering electricity and the computer that runs the mining software to be free.
Even if the price increases tenfold by surprise and I overclock my ASIC to the limit that's not going to be good enough, right?
Seeing that I want to know why do people spend hundreds of thousands of dollars mining bitcoins. I don't know, but I would assume that a 2TH/s ASIC might produce thousand times the output of my ASIC, but it will cost more than 1000 times the price of mine, or not? And with so few bitcoins per hash/s it doesn't really matter how many hash/second you own, right? Each single hash/second is just a sunken cost, no matter how valuable Bitcoin get.
It would be really great if anybody could explain why there is a single person who mines for money.
edit: what I mean is owning a 2 TH/s ASIC must earn more than 1024 times more than a 2 GH/s ASIC for it to even have a chance to make it's own cost back, right? Is there such a thing? Does a TH/s get 2000 times more bitcoins than a GH/s?
edit 2: I might need to add some perspective on my expectations. I've read a lot of articles. So after that I knew I will not make a profit. But expecting to make 80% of your investment is one thing, then experimenting and actually not making 1% of your (small) investment is really, really bad.
edit 3 - Summary of the discussion results up to now: For people who don't want to read all the comments, the result is that I probably paid way too much for my ASIC when comparing GH/s to the price of the ASIC. I paid about 17.5€ per GH/s while a normal price would be around 0.40€ per GH/s. To get that result you probably need to invest bigger than 35€ and buy a bigger ASIC, though.

Unsure if scam or mixup. Need other input on BitcoinWare.net from experienced buyers.

My boyfriend and I recently got into mining and planned to start small and get bigger. We saw that BitcoinWare.net had a Canada Day sale with free shipping and a sale on Antminer U2 units, so thought that it would be a good place to start with minimal investment. So we dropped $60 on 3 units, received a confirmation email and could check the status on the website.
A few days after that though, I received an email from them saying that they had over sold the U2 units and asked if I would rather the option of: a) a full refund. b)wait 1-2 weeks for the units to restock for shipping. or c) to change my order to another item on their site using the already paid money as a credit towards the purchase.
We opted to wait for the U2 units (as they were $20 a piece), and sent them an email immediately.
almost 2 weeks went by without word back from them before my boyfriend noticed that the U2 units on their site were in-stock. So we sent them another email inquiring on the status of our shipment and within 2 hours we received 2 emails. an email confirmation of shipping and one stating that they apologize for the delay and asking if we received confirmation that the shipment was sent. We responded that we received confirmation and that we were happy with the timeliness.
That was the last time we had heard from them.
Within a week we received the package, but upon opening the package, there were 3 units, but all of them were U1 units, Not U2.
We immediately emailed them inquiring as to what could have happened and if there was any way to remedy the situation. However, that was over a day ago and we have not received word from them in any way.
Their website is only 4 months old, about as old as their Reddit User account u/bitcoinware .
TL;DR Paid for 3 U2 Antminers from BitcoinWare, received 3 U1 units after asking what happened to our order.
Has anyone else had similar experiences with this seller or any sellers like this? If so, what happened? and what do?
Edit: Finally heard back from BitcoinWare.
Hello,
We received your emails and contact form submission, sorry for the delay in responding. The U1/U2 are the same thing. They both use the same chips and can achieve the same hash-rate in our testing with the same settings. The only difference is the shape of the heatsink. Since the factory does not make this product any longer, they were shipping both types in the same batch just with different heatsinks for the last shipment.
Please note it states on the product page: "The color and the shape of the heat-sink and product appearance may vary slightly from the pictures."
If you are not satisfied, you can return the products for a refund. Alternatively we can provide you a discount for future orders if there is a problem with the products you received. Please let us know how you would like to proceed.
Best regards, BitcoinWare
...Pretty sure this is a scam now...
What I got.
What they are advertising.
Receipt that came in the envelope with miners
Edit2:
So BitcoinWare has sent me an email saying that they would be willing to offer a full refund with the option of keeping the units because I was unsatisfied with what I had received. The reason is due to the information they were provided by their supplier, so they did not intentionally misrepresent their product as U2s. Previous clients apparently where fine with what they received so it had never been an issue for them before.
I've replied asking to settle instead on $6 off the total order ($2 a unit) for the cost of purchasing proper heatsinks for the units and materials to attach them so that I'll be able to get the 2GH/s promised on their site. I have yet to hear back.
I think in the long run I don't believe that these people are a scam, but it's probably best to get confirmation of product prior to shipping in the future.
Final edit: They sent me a $10 refund so I can buy heatsinks so that's all settled with.
TL;DR: Though their supplier sounds sketchy, BitcoinWare is not a scam and are just really slow at getting back to you. Confirm before ordering, but you will get products.

P2POOL NODES UP!

We just unleashed the Panda-Beast on the p2pool network..
In times of pools getting hashrates above of 2gh/s (by a total net hashrate @ 4.2 gh/s) its time to prevent the 51% by using a decentralized way of mining.
In short: "Mining solo in a group" :-) For everyone who never heard about p2ool and for everyone who wanna escape pool operators, ddos attacks and high pool and transaction fees:
read: https://en.bitcoin.it/wiki/P2Pool
Just point your miners to one of the two nodes by using your ThePandaCoin WalletAddress as your Username
example:
"vertminer --scrypt-vert -Q 0 -o stratum+tcp://.....:9190 -u PayoutAddress -p anything"

Mining Calculations/Questions

Hello everyone! I'm looking into getting into mining scrypt currencies like Litecoin and ran into some vary weird calculations that just can not be accurate, but I'm not sure what could be wrong.
I found this miner: http://www.amazon.com/BITMAIN-ANTMINER-U2-Bitcoin-Overclockable/dp/B00ITD5NV6/ref=cm_cr_pr_product_top
It claims to do 2 GH/s which seems crazy as it is. So I was curious about how profitable it would be. So I Googled "Litecoin mining calculator". I found this website: http://litecoinminingcalculator.com/. It asks for kh/s for their calculator. So I enter in what the 2GH/s would be and unless my math is wrong it should be 2,000,000 KH/s. At that rate it estimates I will mine 191.25 Litecoin a day at the current difficulty of 10,307.9291509 (could this be wrong?) At 191.25 LTC a day that is 67415.09 LTC a year. That has to be wrong isn't it? That's absolutely absurd number. Something has to be wrong, but I'm not sure what it is. Any ideas?

Block erupter issue

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.

ASIC Miners?

Hey guys, I'm new around here. I have seen multiple "coin miners" on sites and a couple advertising for 2GH/s Speeds. Like this one here: http://www.amazon.com/BPMC-Fury-2-2-2-7-Bitcoin-Minedp/B00GRJUE0Y/ref=sr_1_2?s=pc&ie=UTF8&qid=1399944259&sr=1-2&keywords=coin+miner
Not sure if good deal or no? Or what the actual usage would be for DogeCoin mining as in the mining pool im in only utilizes a max of 700MH/s... Any help is greatly appreciated!!

Did I just do something really stupid?? Bought new Mobo and case to reactivate 4 5870s

I still had 4 5870s kicking around, so I thought I could reactivate them. Went to the next store and ordered a shiny new mobo with 6 PCIe slots, CPU and a case for the whole thing.
Now, I have been catching up a bit and saw that ASICs are all the rage. With my gear I should get about 1.2gh/s... at the same time you have these:

What gives? Is this really happening? GPU mining dead with this?

Asking questions

So I've decided to join the illustrious pursuit of Bitcoin mining. I've done a bit of research on the matter, and read over a few of the posts here. And I still have a lot of research to do yet. My first problem is that there's still a lot that I'm not sure about and I'm still new enough that I don't quite know the right questions to ask, or if the questions I'm trying to ask are even applicable. So, I wanted to outline my situation and some of my thoughts here and see if this great community could help direct my research.
To start off, I purchased my ASIC hardware today, and I'm awaiting delivery. I managed to get a total of 13.2GH/s for less than $300, which seemed like a good buy. It's more MH/s per $ than the $350 USB device that butterfly labs was offering. I know that's pretty weak, but it's where I've decided to start. It's good enough for getting my feet wet.
My first real question is regarding the network bandwidth requirements of an active mining setup. All of the online guides I have read have said absolutely nothing to this issue. Common sense would tell me that this is either a negligible concern or in some other way, so bluntly obvious that it doesn't bear mentioning. So at the risk of sounding dense, can anybody describe their situation in this area? I've got a 12Mb/s DSL connection, will that be a bottleneck issue or will it suffice?
As I've come to understand, my next steps are to setup a wallet for the currency, join a user pool and setup a mining client. And it's these steps where my questions begin.
The most popular choice among the webz for walltes was easily Bitcoin Armory, but the 6GB RAM requirement is a nonstarter for my current hardware setup. I understand that they are working to reduce that requirement and that, also, there are hardware wallet modules hitting the market soon. Until one of the two options becomes available, I'm looking at utilizing a third party, web based wallet. Any suggestions in that regard would be appreciated. But my first concern with a wallet is that I am very interested in mining cryptocurrencies other than Bitcoin. I haven't been able to get an answer as to whether or not I will need an individual wallet for each unique currency I mine or if wallets generally support more than one currency type.
Reading through a number of the beginner's guides found through google gave me the impression that installing a mining client and joining a mining pool were separate issues. But a thread I read here seemed to indicate that particular clients were tied to specific mining pools. Preferably, I'd prefer a client that would allow me to select a mining pool, as well as supporting mining for Bitcoin as well as multiple other cryptocurrencies. Is that a realistic expectation?
If the tone of any of my questions suggest any broad misconceptions, I would appreciate a heads up. If anybody can link to some helpful literature on the subject, that would also be appreciated.
Thanks for reading, and cheers for any help.

I am just starting doing this as a hobby and need some help.

So I bought a BITMAIN ANTMINER U2 2Gh/s USB Bitcoin ASIC Miner, and downloaded BFGminer and that is as far as I could figure out what I have to do. So I was just curious what are next steps I have to take to get mining. Thank you in advance.

[WTS] Antminer U2s (2.0GHs) - $20 each

Uncle Bubs is selling three Antminer U2s. These are USB sticks that mine sha256 currencies at 2.0GHs (manufacturer recommended, although I run them at 2.2GHs with no problem), using almost no power (2 watts). Included when you buy from me is a quick start kit, including BFGminer preconfigured to work with your Antminer, the device drivers, and a tutorial on how to start mining. All of my miners have been tested to verify they work and overclock properly.
Antminers can be seen on Amazon here for $27.50; I’m selling mine for $20 plus $1.99 shipping, or free shipping if you buy all three. The price is the Coinbase price in USD at the time of sale. Ships to the United States only.
Uncle Bubs accepts Bitcoin as payment; contact me at [email protected].
Or, if you’re more comfortable with credit card transactions, you can buy them at my Ebay auction. Note that, while you may see some on Ebay for around $14, those are auctions. Having tried and failed many times to buy something from an Ebay auction only to be outbid at the last second (literally the last second), I only use “Buy it Now” now.
Antminers will mine any sha256 currency, including (but not limited to):

GPU, FGPA, ASIC mining and 2 minutes attention.

Hello, for those who think GPU is out of business is wrong. Actualy they do over 99% of the bitcoin mining, becayse of the price/mh of the FGPA and non existence of ASIC's. Regular FPGA boards just output hash power like RADEON 5770 - 200Mh/s for a hardware cost 5 times 5770, and you still need PC to operate with FPGA board.The long waiting ASIC's never realised and not will soon, until theese days ASIC's are considered as scam. But may i have your attention. I have small tech company based in Sofia , Bulgaria (european unit). I made some research on custom hardware for bitcoin mining. The problem is that the good FPGA chips that can output reasonable hash power costs several thausands dolllars each. I found good alternative with one chinese chip manufactorer but still the working prototype will be an expensive investment, at least for me. What i want to build is device that is capable of 2GH/s with own web server and internet connection for pool mining management (because you dont want dedicated PC with the miner) all for retail cost under 500$. The invention will cost around 10,000$ only for materials, my dedicated working hours are not counted and doesnt matter. To reach the 500$ barier two things must be availble- 1st own Pick&place machines (which i dont have), 2nd a good amount of chip order(the more chips, the less the price) for chinese fabric. A good start is around 130,000$, for prototype, pnp machines, and the chip order. What i have is a testing equipment. So if there are persons who want to invest, or donate for my miner all will be welcome. The first 10,000$ will show if it is possible and is considered as risk investment, which i can not return. If the prototype working with the required parametters the money above first 10,000$ will be considered as donation, investment or preorder(every participant can choose what it is). I can't put my company info and email here because i dont want spam, but i can give all details in personal. Only serios mind please, my english isnt good for that i can't argue with everybody in the reddit.
regards
