Bitmine is expected to generate about $334 million in annual revenue at current yields by staking more than 5.06 million ETH, or roughly 85% of its 5.95 million ETH holdings. Staking, which involves committing crypto to support network operations in exchange for rewards, would provide the projected revenue stream. Bitmine bought another 27,180 ETH last week, taking the value of its combined crypto and cash holdings to about $15.8 billion, Cointelegraph reported.
