Bitmine to End Ether Purchases at 5% of Supply, Chairman Says
Bitmine Immersion Technologies plans to stop buying ether once it owns 5% of the circulating supply, according to Chairman Tom Lee. The company currently holds 4.9% of supply, worth about $15 billion. Lee confirmed the 5% limit at the TOKEN2049 conference, stating it is a firm cap. Bitmine shares (BMNR) traded at $24.54, while ether was near $2,566, down 5.73% on the day.
