Product Description
KD2 Gold Shell Miner 6400GH/S 830W Agorithm Blake2S Ethernet Goldshell KDA Miner

As you know, the difference between goldshell KD2 and brother kd5 lies in the improvement of hash rate, power consumption and noise level. Like all of their competitors, the gold shell KD2 and kd5 are made of oversized aluminum and are shaped like PC system units. Large blade fans are responsible for cooling integrated circuits. In fact, they can provide effective heat dissipation.
It's worth noting that goldshell KD2 and kd5 have their own software that instantly identifies errors. Miners restart automatically in the event of a crash, and their software sends emails about various lags that developers can fix in the next update.


Profitability of KD2 and kd5
First of all, goldshell KD2 is more focused on home mining, while goldshell kd5 is more focused on a variety of large-scale mining sites. As of February 23, 2021, goldshell KD2 is mining Kadena cryptocurrency at $31 per day or $935 per month.
As for the gold shell kd5, the profitability here is $94 a day or $2800 a month.
Therefore, the payback period of goldshell KD2 is about 5 months and that of kd5 is 4.5 months.
According to the data of coinmarketcap, Kadena is the 447th largest asset with a total capital of US $39 million. At present, Kadena is supported by exchange giants such as hotbit, coinex and bittrex. In other words, whether bitcoin or usdt stable currency, the cryptocurrency mined can be sold on one of these exchanges without any problem.

Daily mining revenue:


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.
