BitMine Says It Will Stop Buying Ether Once It Hits 5% of Supply
BitMine will stop buying ether once its holdings reach 5% of ETH's circulating supply, according to chairman Tom Lee. The company currently holds 4.9% of the supply, worth about $15.5 billion. BitMine shares fell 7% on the news, while other ether treasury firms also dropped. Lee cited discussions with the Ethereum Foundation as a factor in the decision. The company has been the largest single holder of ether and the biggest ether staker.
