币界网报道：Bit Digital, a Nasdaq-listed crypto mining company, has announced its complete exit from Bitcoin mining to focus exclusively on Ethereum staking. The firm revealed it sold off its remaining Bitcoin mining fleet in Q4 2023, generating $6.2 million in proceeds, and will now allocate all resources to its Ethereum staking operations through its subsidiary Bit Digital AI. Currently staking 14,000 ETH (worth ~$42 million), the company plans to expand its staking capacity to 20,000 ETH by mid-2024. CEO Bryan Bullett cited Ethereum's "programmable nature" and growing institutional adoption as key reasons for the strategic shift, while CFO Erke Huang noted the move improves capital efficiency with lower energy costs compared to Bitcoin mining. The transition comes as Ethereum's upcoming network upgrades are expected to enhance staking yields and functionality. Bit Digital's pivot reflects the evolving crypto sector where staking services gain traction amid Bitcoin mining's profitability challenges.
