BitMine is approaching the end of one of the largest crypto accumulation campaigns conducted by a company. Tom Lee states that the company will stop buying Ethereum when it reaches 5% of the ETH supply. BitMine already holds 6,041,481 ETH, or about 4.9% of the 122.1 million ETH used as reference. At a constant supply, about 63,500 ETH still separate it from its cap.
