Bitcoin mining has received a lot of attention lately.Since Ghash suspended it’s cloud mining operation, many people have been asking a couple of very simple, but important, questions:  Is Bitcoin Mining worth it?Is it possible to profitably mine bitcoins?Well the answer is complicated, and mining bitcoins can be a great financial choice…or lead to financial ruin.Bitcoin mining has a complicated history, but we can learn much from looking at what has happened over the past few years.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.Those who had successfully optimized GPUs, or aquired FPGAs in 2012 and early 2013, as well as those that were able to obtain early ASICs, or were lucky enough to “bet” on the right Bitcoin mining hardware company for the following generations of ASICs have made incredible profit.

However, the business of Bitcoin mining experienced a fundamental shift between when GPUs / 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.Before the ASICs, Bitcoin mining was worth it simply because the difficulty stayed quite close to Bitcoin’s price.This was true for a few reasons: was not perfect, but mining difficulty generally followed a pattern similar to the Bitcoin to USD exchange rate.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.

His comments on it’s mining power, and how many bitcoins it mined, are eye opening: Performance is much higher than announced.60 Ghps was announced.The unit’s cgminer self-reports 67.5 Ghps.bitcoin highest payoutAfter 20 hours of mining, the unconfirmed + confirmed rewards equal  14.98832170 BTC.bitcoin decode scriptThis Bitcoin miner was mining over 15 BTC per day!bitcoin ammoOf course, for anyone involved with mining today, 67.5 GH/s seems like nothing.bitcoin gadget windows xpToday, 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.bitcoin precio historico

In fact, by the time most of the pre-orders were shipped, the machines were barely profitable.I did make a small amount of profit with my batch 2 Avalon ASIC, which I had managed to get up to almost 80 GH/s, but not very much.ethereum mastercardHowever, at that time, the top end GPUs were only capable of mining at a rate of 500 MH/s – 1 GH/s (with 1 GH/s requiring perfect conditions and incredible optimization), and often consumed 200-400 watts of power when mining bitcoins.bitcoin linked credit cardThough, to be fair, Butterfly Labs had successfully produced their first Bitcoin mining “miniRig” in mid 2012, which utilized 18 boards, with 2 45nm FPGAs on each board, and was capable of mining at ~25 GH/s while consuming ~1,260 watts.bitcoin news coindesk

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.bitcoin asic saleThe first miniRig was exceptionally successful, and the powerhouse of the pre-ASIC period.bitcoin bar graphStill, Avalon’s first ASIC, which was based on ancient 110 nm architecture, managed to mine at over twice the miniRig’s rate, for around half of the power consumption, and was sold at a fraction of the cost of the miniRig.bitcoin escrow transactionThese 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.pagare con bitcoin in italia

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.publicly traded bitcoin companiesAs Bitcoin ASICs began with the 110 nm Avalons, which was architecture available in traditional CPUs in the early 2000s, many companies sprung up to work toward out the next generation, with hopes of eventually reaching “state-of-the-art”, which is ~22 nm at the moment.simple bitcoin pythonTo date, I do not know of any commercially available ASICs with <= 22 nm architecture, but 28 nm has been reached.dogecoin value right nowRealistically, the development of truly state-of-the-art Bitcoin mining ASICs may not be worth the investment, as the increase in power efficiency, which is the most important factor for a Bitcoin mining rig, is nowhere near as large as previous generations.bitcoin telegraph

I say “may” because it truly depends on a few factors: 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.bitcoin sports betting exchangeAs long as the link between Bitcoin’s price and the total mining power of the network remain close, then changes in the value of Bitcoin would only effect those that are are barely profitable already, and would do little to change the worthiness of mining.bitcoin 2050This is because miners would be receiving more bitcoins for their hashing power when price and difficulty decline, but less bitcoins as price and difficulty increase.dogecoin highThis chart is continuing where the difficulty chart at the start of the article left off, and includes a projected difficulty decrease on January 17.litecoin gambling

From March 2013 on, the mining difficulty increased exponentially.The last few months seem to have leveled out: However, it could get out of sync once again.A breakthrough in ASIC technology is unlikely in the near future, but certainly possible.ethereum songThat would create a new jump in difficulty, and render older ASICs less valuable, as Bitcoin’s price should not be impacted very much.ethereum trillionAlso, 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.bitcoin al alzaA 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 atm new york

Of course, this scenario would also result in a sharp drop in difficulty when the 2016th block is finally mined, instantly increasing the value of mining power…but, until that point is reached, the Bitcoin network could become quite unreliable and chaotic.bitcoin atm machine new yorkStill, outside of these scenarios, difficulty should continue to stabilize, and somewhat follow Bitcoin’s price.asic bitcoin mining equipmentThis means that yes, Bitcoin mining is worth it in many cases.bitcoin en alzaHowever, whether it is worth it to you is something that only you can decide.bitcoin pool profitabilityJust remember, if you are considering becoming a Bitcoin miner, work through the math before you invest.young bitcoin millionaire
