What is the reason for the fluctuation of hashrate miner?
This is a completely normal phenomenon. The mining calculation process never has a stable output, although it is expected to be stable (especially with respect to hashrate and earnings). In addition, mining is also affected by the condition of the machine, the mining environment, the stability of the mining network and many other factors. In order to maintain the most stable earnings, it is necessary to ensure as many of the above factors as possible.
