Bitcoin mining machine is a computer used to earn bitcoin. Generally, these computers have professional mining chips, which mostly use the way of burning video cards, which consumes a lot of electricity. The user can download software by personal computer and run specific algorithm. After communicating with remote server, the user can get corresponding bitcoin. It is one of the ways to obtain bitcoin.

Mining is actually the competition of performance and equipment, and it is the competition between miners. The probability of mining bitcoin is greater for miners with more calculation power. With the increase of the whole network computing power, it is more and more difficult to dig bits with traditional equipment (CPU and GPU). People have developed chips specially used for mining. Chip is the core part of the mine machine. The chip will generate a lot of heat during the operation. In order to cool down the heat, bitcoin machine is generally equipped with heat sink and fan.

Before calculating the mining revenue, we should first understand several concepts: Difficulty, Hashrate, Block Reward, and 24h Estimated mining revenue. Take BTC for example:

Calculation of BTC mining income

Bitcoin shows how difficult it is to mine through multiple transforms, it can be simply understood as: assuming the corresponding mining difficulty is “1”, it takes about 232 times hash operating, in order to get a random number needed for a legal new block in theory, that is mining a legal new block theoretically.

So, it can be inferred that, when the mining difficulty is D, (D×232) times hash operating are needed to dig a legal new block, and R units BTC can be obtained as a block reward. If the miner's computing ability is H, then the time it takes him to complete (D×232)times hash operating equals (D×232) /H seconds.

Theoretically, the miner's mining revenue per second equals R÷ (D×232) /H BTC. 24 hours a day, a total of 24×60×60 seconds, the estimated daily mining revenue of BTC as below:

P=Hx 1/(Dx 2^32)R x (24x60x60)

For example:

Current BTC difficulty D=12720005267390.51

Reward per BTC block R= 12.5BTC

1Ph/s hashrate

Daily mining revenue= 1x10^15 x(1/12720005267390.51x 2^32)x12.5x24x60x60,

Available: P= 0.01976863 BTC

BTC and ETH are two typical crypto currencies. The mining revenue calculation of other currencies are similar to these of BTC and ETH.

We specialized in distributing ASIC cryptocurrency mining equipments to worldwide more than 5 years, with very high reputation and credibility.

Just in this year, we have signed an annual purchase agreement with Bitmain, and we will order at least 1000 mining machines from bitmain every month. Of course, this is only a part of our goods source, we have enough strength to provide the corresponding brand and model according to the needs of customers.
