BitMine Immersion Technologies bought an additional 10,399 ether last week, lifting its total holdings to 5,797,813, according to Decrypt. The purchase was worth about $19.5 million and leaves BitMine holding about 4.8 percent of circulating supply. The company put the value of its ether holdings at about $10.9 billion and total assets at $11.3 billion. It also repurchased 4.5 million shares under a $4 billion program and said about 85 percent of its ether is staked via Mavon.

Bitcoin rebounded to $66,921 but slipped back into the $63,000 range, prompting warnings that the move may be a bull trap rather than a trend reversal. Broader crypto prices fell and liquidations exceeded $670 million, mostly long positions. Risk-off sentiment spread from a sharp drop in South Korean stocks to global markets. Traders trimmed leverage ahead of the Fed meeting, while technical indicators and prediction-market bets leaned toward a move to $55,000.
