How to get started with Bitcoin mining.
Before we begin Before you read further, please understand that most bitcoin users don’t mine! But if you do then this Bitcoin miner is probably the best deal. Bitcoin mining for profit is very competitive and volatility in the Bitcoin price makes it difficult to realize monetary gains without also speculating on the price. If you want to get bitcoins based on a fixed amount of mining power, but you don’t want to run the actual hardware yourself, you can purchase a mining contract. Another tool many people like to buy is a Bitcoin debit card which enables people to load a debit card with funds via bitcoins.
Bitcoin mining is a lot like a giant lottery where you compete with your mining hardware with everyone on the network to earn bitcoins. For each new hash that is tried, the mining software will use a different number as the random element of the block header, this number is called the nonce. 93ef6f358fbb998c60802496863052290d4c63735b7fe5bdaac821de96a53a9a You can look at this hash as a really long number. It’s a hexadecimal number, meaning the letters A-F are the digits 10-15. To ensure that blocks are found roughly every ten minutes, there is what’s called a difficulty target. To create a valid block your miner has to find a hash that is below the difficulty target.
00db27957bd0ba06a5af9e6c81226d74312a7028cf9a08fa125e49f15cae4979 Because the target is such an unwieldy number with tons of digits, people generally use a simpler number to express the current target. This number is called the mining difficulty. The mining difficulty expresses how much harder the current block is to generate compared to the first block. To keep blocks coming roughly every 10 minutes, the difficulty is adjusted using a shared formula every 2016 blocks. The network tries to change it such that 2016 blocks at the current global network processing power take about 14 days. That’s why, when the network power rises, the difficulty rises as well. GPU About a year and a half after the network started, it was discovered that high end graphics cards were much more efficient at bitcoin mining and the landscape changed.

The massively parallel nature of some GPUs allowed for a 50x to 100x increase in bitcoin mining power while using far less power per unit of work. FPGA As with the CPU to GPU transition, the bitcoin mining world progressed up the technology food chain to the Field Programmable Gate Array. With the successful launch of the Butterfly Labs FPGA ‘Single’, the bitcoin mining hardware landscape gave way to specially manufactured hardware dedicated to mining bitcoins. An ASIC is a chip designed specifically to do one thing and one thing only. Unlike FPGAs, an ASIC cannot be repurposed to perform other tasks. An ASIC designed to mine bitcoins can only mine bitcoins and will only ever mine bitcoins. Unlike all the previous generations of hardware preceding ASIC, ASIC may be the “end of the line” when it comes to disruptive mining technology.

CPUs were replaced by GPUs which were in turn replaced by FPGAs which were replaced by ASICs. There is nothing to replace ASICs now or even in the immediate future. Bitcoin Mining Software There are two basic ways to mine: On your own or as part of a Bitcoin mining pool or with Bitcoin cloud mining contracts and be sure to avoid Bitcoin cloud mining scams. Bitcoin Cloud Mining By purchasing Bitcoin cloud mining contracts, investors can earn Bitcoins without dealing with the hassles of mining hardware, software, electricity, bandwidth or other offline issues. Being listed in this section is NOT an endorsement of these services and is to serve merely as a Bitcoin cloud mining comparison. There have been a tremendous amount of Bitcoin cloud mining scams.

Bitcoin mining has received a lot of attention lately. What Made Bitcoin Mining Worthwhile Before? Mining bitcoins has been a very profitable venture for a very long time. While many people who tried Bitcoin mining failed to profit, didn’t receive their mining rigs due to fraudulent or inept companies, or barely reached a positive ROI on their Bitcoin mining attempts, that was not true for the more experienced miners. FPGAs were the norm, and the rise of ASICs bitcoin mining hardware. These ASICs completely changed the game by increasing the efficiency of mining bitcoins by many orders of magnitude, and completely destroyed the profitability of mining with a traditional computer.
Why Mining Bitcoins With GPUs Was Worth It Until 2013 Before the ASICs, Bitcoin mining was worth it simply because the difficulty stayed quite close to Bitcoin’s price. Many Bitcoin miners were only mining part-time, and were simply using GPUs that they already had purchased for gaming to mine when they were not using their computer. This completely removed the equipment cost from the ROI equation, as the ability to effectively mine bitcoins was just a benefit of having a decent gaming computer. At that time, there were very few huge Bitcoin mining farms.
A large portion of the mining community, at that time, were not mining for profit alone. FPGAs began to skew this slightly in 2012, then ASICs shattered it completely. In early 2013, Jeff Garzik received the first Bitcoin mining ASIC, produced by Avalon. While one other company may have produced a functional BTC mining ASIC around the same time, Avalon was the first to develop, manufacture, and sell these incredible mining rigs to the public. His review of the Avalon ASIC confirmed that not only was Bitcoin mining worth it, but could be incredibly profitable. Performance is much higher than announced. This Bitcoin miner was mining over 15 BTC per day!

Of course, for anyone involved with mining today, 67. Today, one would be lucky to get 0. 0007 BTC per day with that hashrate, according to our Bitcoin mining calculator, and the fact that it used over 600 watts of power, makes operating the machine a losing proposition. 200-400 watts of power when mining bitcoins. For those of you that did not know why Butterfly Labs was so trusted by the Bitcoin community, or did not understand why so many people were willing to pre-order their ASICs, this is why.
These machines started a revolution in mining that resulted in the Bitcoin network containing a level of processing power that has never been reached before in human history. Is Bitcoin Mining Worth It In 2018? Yes and no, depending on your situation. The emergence of ASICs created an arms race that made investing in Bitcoin mining machines more volatile, and risky, than Bitcoin itself. How much electricity does your miner consume?

This miner is a solo miner. It has a small chance of mining a block but does not generate monthly revenue. How to Determine Potential Bitcoin Mining Profitability So, that brings us back to the central question of this article. Is Bitcoin mining truly worth it? Over the past year and a half, I would have advised against it, and said no.

It did have the potential to be profitable, but it was too much of a gamble. However, with the availability of 28 nm ASICs, as well as 45 nm ASICs that can be modified to reach nearly the same efficiency as the 28 nms, and the fact that Bitcoin’s difficulty seems to be stabilizing, then Bitcoin mining may be worth it for you. As has always been true, your personal cost of electricity is extremely important. However, this is not nearly as important as it was while Bitcoin mining ASICs were experiencing incredibly fast leaps in efficiency. Now, with a bit of work, and a decently priced machine, even people with average electricity costs can mine bitcoins profitably. Because so many people were burned by a combination of price drops, exponential increases in difficulty, the speed at which Bitcoin ASICs evolved, or delayed delivery of machines, there are an abundance of used 45 and 28 nm ASICs available for sale. The people selling these may live in an area where Bitcoin mining isn’t worth it, for whatever reason, or they may just be tired of it after the roller coaster they have been on for so long.
Others may be just trying to hedge their bets, and break even on their investment through a combination of the bitcoins they mined and revenue from the sale. Examine any potential ways you could utilize renewable energy. This will increase the efficiency of the machines, as processors run more efficiently at cooler temperatures. In warmer areas, this is reversed:-Your BTC miners may end up requiring more power than just the amount consumed by the mining rigs themselves. If it is warm enough for your air conditioner to be running, then it must counteract the heat put out by your machines.

This could be the difference in Bitcoin mining being worth it for you to invest time, and money, into, or not. Bitcoin’s Price Does Impact Bitcoin Mining’s Worth While the Bitcoin mining difficulty is now more likely to fall into a closer relationship with Bitcoin’s price, the link doesn’t guarantee stability. However, it could get out of sync once again. A breakthrough in ASIC technology is unlikely in the near future, but certainly possible.
That would create a new jump in difficulty, and render older ASICs less valuable, as Bitcoin’s price should not be impacted very much. Also, as difficulty is only adjusted every 2016 blocks, sharp declines in Bitcoin’s price can make it so that mining is not very cost effective until the difficulty adjusts. A sharp enough Bitcoin price drop could, effectively, cause enough miners to be turned off that it takes a very long time to mine enough blocks to reach the difficulty change. Bitcoin network could become quite unreliable and chaotic. Still, outside of these scenarios, difficulty should continue to stabilize, and somewhat follow Bitcoin’s price. This means that yes, Bitcoin mining is worth it in many cases. However, whether it is worth it to you is something that only you can decide.
Just remember, if you are considering becoming a Bitcoin miner, work through the math before you invest.
