Bitcoin’s next difficulty rise could leave some rigs earning less than their power bill
Summary
Bitcoin’s next difficulty adjustment, projected around Oct. 16, is expected to raise mining difficulty by 5.68%. If Bitcoin’s price, block subsidy and average fees remain unchanged, estimated hashprice would fall 5.37%, from $39.77 to about $37.63 per PH/day. For equipment using 20 J/TH, the electricity-only break-even rate would decline from 8.29 to 7.84 cents per kWh. Miners with high power costs or less-efficient machines could become unprofitable, while more efficient operations may retain a cushion. The projection is based on a dashboard reading before the adjustment and may change; actual revenue will also depend on Bitcoin’s price and fees.
