Bitcoin’s next difficulty rise could leave some rigs earning less than their power bill

Bitcoin’s next difficulty adjustment is expected to raise the cost of mining each block, reducing revenue per unit of computing power. With Bitcoin prices and transaction-fee income unable to offset the increase for every operator, some rigs—especially those with older equipment or high electricity costs—could earn less than they spend on power. This may pressure less efficient miners to shut down or upgrade, while making access to cheap energy and efficient hardware more important for staying competitive.
