According to a report by CryptoQuant, transfers from Bitcoin (BTC) mining pools to exchanges reached their highest level in two months this week as BTC hovered around $70,000. The Bitcoin halving has led to a drop in daily mining revenue, with miners looking to make a profit by selling their bitcoins through the over the counter (OTC) platform. On June 10, miners sold at least 1,200 bitcoins, the highest daily volume in two months. Since the beginning of June, Marathon Digital has sold 1,400 bitcoins, worth $98 million. The daily revenue for miners was $35 million, down 55% from the peak of $78 million in March, the report added.
