Ethereum is currently mining at a record low of $0.0169 a day per MHash, according to bitinfocharts. If the mainstream miner whose calculating force is 240MHash/s is taken as an example, it is calculated at 0.4 yuan per degree of electricity price, the daily mining cost of a single miner is 9.22 yuan, and the daily net profit is 15.10 yuan. The current ETH price is 1,346 yuan, the computing power is 271.23T, if the ETH price is less than 507 yuan ($74), the daily earnings of ethereum miners may be zero.
This is often caused as a result of high mining difficulty which does not limit to ethereum coin alone but to any POW coins.
By your currency denomination i can understand that you are from China, has Chinese government allow crypto mining again ?
