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.

Two data algorithms,
Can switch between HNS and SC mining modes by simply switching firmware,
Compared with the hs3, 35% more computing power, power consumption reduced by 2%.

Model HS5 from Goldshell mining 2 algorithms (Handshake, Blake2B-Sia) with a maximum hashrate of 5.4Th/s for a power consumption of 2650W.

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.
