    Bitcoin mining revenue

    The Bitcoin network saw a change of -4.33% in the hashrate on 2022-05-25, the biggest negative percentage change in the recent 10 months. As the price fluctuates to around $30,000, the past 2-week cycle was recorded with the mining revenues of $0.12 per 1 TH/s.

    More ASICs approach their breakeven prices. At the time of writing, miners with unit power of 60W/T could barely generate profits since the electricity cost rate was around 95%, and the cost rate for miners with a unit power above 65 W/T was more than 100%. This means that their electricity costs had exceeded the revenues that could be brought by the miners at the power rate of $0.08 per kWh.

    The Ethereum network has experienced a drop in hashrate, from its ATH of 1126 TH/s to the recent 1064 TH/s. The unit revenue also fell down from a level around $0.3 to $0.24 per 1 MH/s. The fall was expected to be affected by the market downturn and the difficulty bomb, which gradually slowed down the block production.
