KD5 from Goldshell mining Kadena algorithm with a maximum hashrate of 18Th/s for a power consumption of 2250W.
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.
Warranty Tips:
1, Generally, the second hand miners without warranty ,or the warranty expired.
2, Second hand miners are not allowed to be return, replacement or refund.
3, The shipping with remote distance, carefull check the situation of the package avoid the loss due to the freight.
4, Some parts maybe get loosen due to the very distance freight, please ask professional person who be familiar with this field to check or repaire it.
