币界网报道：Nasdaq-listed Bit Digital (market cap $488M) is shifting its focus entirely to Ethereum staking and treasury operations while exiting Bitcoin mining. The company has started exploring strategic alternatives for its Bitcoin mining division, potentially leading to a sale or shutdown, with proceeds to be reinvested in ETH-related activities. Since 2022, Bit Digital has been accumulating ETH and developing staking infrastructure, currently holding 24,434 ETH ($44.6M) and 417.6 BTC ($34.5M) as of March 31, with plans to gradually convert remaining BTC to ETH. Ethereum's proof-of-stake transition post-Merge (September 2022) enables firms to earn 4-6.5% annual yields through staking, attracting companies like Bit Digital and SharpLink Gaming seeking crypto-based passive income. SharpLink recently secured $425M in funding led by Consensys to expand its ETH treasury holdings to 188,478 ETH ($490M).
