The Ethereum Foundation has now staked roughly $143 million worth of ether, effectively completing its previously announced 70,000 ETH staking target. The move shifts the foundation from regularly selling ETH to help fund its roughly $100 million in annual expenses toward earning staking yield of an estimated $3.9 million to $5.4 million a year instead. The Ethereum Foundation staked roughly $93 million in ether (ETH) on Thursday in several batches, bringing its total staked position to approximately $143 million and nearly completing the 70,000 ETH staking target it announced in February, according to Arkham data. At roughly $2,059 per ETH, the $143 million total staked position works out to approximately 69,500 ETH, nearly the full 70,000 ETH commitment. The foundation had been building toward the target incrementally since February, starting with an initial 2,016 ETH deposit and adding roughly 20,470 ETH on Monday. Thursday's batch covered the remaining balance in one shot. The Ethereum Foundation says that it is putting its ETH holdings to work through staking, earning rewards that help fund research, grants, and operations — all without selling its coins. This new approach differs from the previous model where the Foundation resorted to ETH sales to generate cash. The Foundation faced criticism over its frequent token sales.
