最新报道:Bitcoin mining firm Marathon Digital (MARA) has adopted a new strategy of holding all mined BTC in its own custody rather than third-party custodians like Coinbase. The company mined 1,853 BTC in Q4 2023, bringing its total holdings to 15,174 BTC worth $650 million. CEO Fred Thiel cited growing institutional interest in Bitcoin, including BlackRock's spot Bitcoin ETF approval, as validation for self-custody. Marathon also plans to expand into Ethereum staking, anticipating potential ETH ETF approvals. The move reflects miners' shifting strategies amid evolving crypto regulations and institutional adoption trends.
