Data: miners' daily earnings down 75% since April halving

Miners' daily revenue has fallen 75 percent to $26.5 million since it was halved in April, CryptoQuant data showed. Transaction fees earned by miners have fallen to 3.7 percent of total revenue after jumping to a high of 75 percent earlier in the month. Le Shi, head of trading at market-making and algorithmic trading firm Auros, said the $51,000-$52,000 range is critical because many bitcoin miners are reaching the break-even point for profitable mining.
