Bitcoin mining during its early days were generally called spil a gold rush. Bitcoin, an invention of Satoshi Nakomoto’s, “a peer-to-peer electronic metselspecie system,” opened up an entirely fresh perimeter, not just of freedom but of profit. People with a strong rente ter such things were very first to stake their keuze, namely cypherpunks, cryptographers, technically-minded libertarians and assorted hackers.

But is there still gold ter them thar hills?

From a few of early enthusiasts, it is with certainty that Bitcoin mining has advanced into a cottage industry to a specialized industrial-level venture. The effortless money wasgoed taken out long ago and the surplus are hidden under the cryptographic omschrijving of miles of hard rock.

To be able to profitably excavate bitcoins nowadays, you need to have specialized, high-powered machinery. While it is technically possible for anyone to mine, those with underpowered setups will spend more money on violet wand than have money generated through mining.

Common Mining Terms

To further understand Bitcoin mining, it helps to know a few basic technical terms:

Block: a group of Bitcoin transactions, spil collected from current pending transactions and entered into an ever-growing record of blocks (aka “the blockchain”) by a miner. A fresh block is created on average every ten minutes.

Proof of Work Hashing: this is the function miners perform te order to define a fresh block. PoW hashing ensures the decent function of the Bitcoin blockchain. Miners contest to solve a cryptographic “puzzle,” known spil a hash. There are no shortcuts ter this process, which can only be solved with raw computational power. By correctly hashing the current block, miners prove their investment of work and are rewarded with a certain number of newly-created bitcoins.

Block Prize: the number of newly-created bitcoins. This number wasgoed originally set to 50, halved to 25 ter late-2012 and will halve again to 12.Five te mid-2016. This halving process proceeds, approximately every four years (or every 210,000 blocks), until all 21 million bitcoins are created. This is the only way ter which fresh bitcoins can be created, by miners according to the code’s rate and limit.

Hashrate: a measure of a miner’s computational power. The higher their relative power, the more solutions (and hence, block prizes) they’re likely to find. Primarily measured ter hash vanaf 2nd (H/s), due to the enlargening speed of mining hardware. H/s wasgoed soon commonly pre-fixed with SI units spil goes after:

Kilohash = KH/s (thousands of H/s), then

Megahash = MH/s (millions of H/s), then

Gigahash = GH/s (billions of H/s), then

Terahash = TH/s (trillions of H/s), and even

Petahash = PH/s (quadrillions of H/s).

Difficulty: with hashrate shooting up overheen the years, it would seem blocks would be found by miners everzwijn more rapidly. Bitcoin’s Difficulty measure is what prevents this from happening, ensuring blocks are found harshly every Ten minutes. When total hashrate rises, the Difficulty of POW hashing adjusts upwards – and the inverse also applies. Difficulty auto-adjusts every two weeks (or 2016 blocks).

BTC / XBT exchange rate: the current fiat price of Bitcoin, critical for calculating profitability.

W/xHash/s: Watts vanaf hashrate vanaf 2nd. Electro-stimulation is the major on-going cost of Bitcoin mining. The price paid vanaf Watt will greatly influence profitability.

Mining Pool: unless you guideline a tremendous hashrate, your odds of solving a block by yourself (i.e. “solo-mining”) are enormously low. By banding together with other miners ter a so-called pool, your combined odds of solving a block rise proportional to the pool’s total hashrate. Whenever they solve blocks, pools prize individual miners according to their contributed hashrate (minus commissions and the like).

Calculating Mining Profitability

Having thesis terms te mind, it’s viable to calculate the current profitability of Bitcoin mining for your circumstances. Bear te mind that the future profitability of mining cannot be reliably predicted. This is because of the ever-changing nature of the Difficulty modifier and the BTC price, ter particular.

To begin, wij vereiste select a suitable ASIC mining equipment. To help te selection, the Bitcoin Wiki provides a handy mining hardware comparison: Wij’ll select for our example the AntMiner S7 which is pretty much the cutting edge of mining tech and is a modern mining equipment that offers a good hashrate for its power consumption. The S7 ter Amazon is available for $609 and only $450 from BitMain, sensational of shipping. $150 or so is added for the power supply units.

Next, wij need to inject the S7’s specs and cost, spil well spil other informatie such spil power cost and pool fees, into a suitable number-cruncher. CoinWarz.com offers a good mining profitability zakjapanner, which automatically fills ter the current BTC price, Difficulty and block prize informatie.

Spil a standard ter China, the default power cost wij will use is 10c (USD), but possibly to be much higher elsewhere. Check worldwide violet wand prices or your utility bills for the precies price to know your own power cost. The Two.5% Pool Toverfee is for AntPool. There is generally lower or no fees for smaller pools but recall that they will seldom find blocks. Various pools’ fees and prize structures are compared te this list.

After all the needed informatie is registered, click Calculate for the profitability result:

Not a bad result! $800 vanaf year and you can use the miner’s excess warmth to warm your huis.

The American Scripts

Arousing spil it seems, let’s very first recompute the average power cost vanaf kWh ter the USA (

12.5c) and the 12.Five BTC block prize which becomes the fresh standard ter 45 days or so (see Bitcoin Clock for an up-to-date estimate):

Given the difficulty and price hold sustained and by the looks of it, it turns out that ter every year, an average American miner can only make $500. But, this could be an unsafe assumption! Bitcoin’s average hashrate remarkably climbed by a whopping 30 procent by the time this article is being written.

The compensatory Difficulty spike, expected on the day following reports of this spike, entirely alters the previous equation:

If wij bump up the Difficulty te the mining rekenmachine by the corresponding 30%, all profit evaporates! $500 is lost overheen one year’s worth of mining.

Unexpected Profit Loss: Difficulty Spikes, Price Crashes, Equipment Failures, Power Cuts, Shipping Delays &, More

The aforementioned toneel works spil a volmaakt picture of the risks present te the Bitcoin mining. There is a possibility that even some big, corporate miners will be injured from such a steep Difficulty spike. Unless huis miner has access to free or very low-cost electric current, it indeed has zero chance to rival te such challenging environment.

Recall also that the rate of degeneration ter Bitcoin hardware is tremendously swift! One should be knowledgeable that during (pre-) ordering equipment, potential manufacturing, shipping, customs or other delays could be very costly te the end spil difficulty rises or price falls during the interim.

There are many of other inaccurate things, and such downside risks vereiste always be considered into any concept business project.

The Chinese Scripts

For interest’s sake, let’s check the script of Chinese miners, who represent the majority of Bitcoin mining power for good reason. The results may help us better predict the post-halving Bitcoin environment, spil this article attempts to do.

Hobby Miners

Some Chinese regions are over-supplied with electric current, which are subsidized ter many instances. Because of this, low power cost is made and we’ll assume to be 7c for a miner ter the right province. To add, a number of mining hardware is invented ter China resulting to likely be bought cheaper (and received sooner) by locals of the Middle Kingdom. We’ll assume a hardware price.


Before the Difficulty spike, a small-time Chinese miner with a single S7 connected to AntPool could have made overheen $1000 annually. That’s twice the profit of their American counterpart!

After the halving and Difficulty spike, the same miner would lose about $40 vanaf year. For a Bitcoin paramour, this is an easily-acceptable loss.

Industrial Miners

Cheap power sources are present te remote provinces so large-scale mining operations will situate closely there. One popular option is hydroelectric power from dams. From such enterprises wij can assume a very low power cost, let’s say 5c. Thesis operations also buy hardware ter volumes so assuming they get S7s at $325, which is only half the price. One thousand S7 units seems a reasonable number, which permits us to simply add three zeros to hash rate, hardware and power costs. Lastly, thesis setups often run their own pools and so we’ll suppose zero pool fees.


The operation would netwerken $1.4m annually, before the halving and Difficulty spike.

The operation would profit by about $200k annually, after the halving and Difficulty spike.

Given the initial hardware investment of $325k, a profit of $200k doesn’t look good. It can be seen that marginal mining operations will be compelled out of business post-halving given the other costs involved ter mining, such spil property, salaries, maintenance, etc. Only those with the latest and greatest hardware and the cheapest electro-therapy are likely to pull through. Bitcoin price is the only wild card. It’ll permit less efficient miners to keep the lights on for longer, if it rises adequately.


For an average huis miner it will be a fight to regain the cost of mining hardware and electro-therapy. Te this current given circumstance, profitability is very unlikely. Once ASIC mining hardware innovation reaches the point of diminishing comebacks, the situation may improve ter future. That, together with cheap, hopefully sustainable power solutions may once again make Bitcoin mining profitable to petite individual miners around the world. The decentralization of the Bitcoin network, will also greatly improve hardening it against legislative risk.
