According to ChainCatcher, Marathon Digital has sold 1,400 BTC worth nearly $100 million since the beginning of this month, according to Coindesk. On June 9, miners sent more than 3,000 BTC ($209 million) to exchanges, most of which came from the btc.com mining pool.

Miners' daily income is $35 million, down 55% from the peak of $78 million in March. The reduction in income can be attributed to the reduction in transaction fees after the halving.
