According to @EmberCN, a new wallet withdrew 52,809 ETH (about $220M) from Coinbase Prime roughly 10 hours ago and distributed the funds to eight wallets that then deposited into Ethereum staking (source: @EmberCN on X). @EmberCN also states that one of the receiving addresses is a known SharpLink (SBET) address and notes SharpLink raised about $200M via a stock sale last Friday (source: @EmberCN on X). For trading context, staked ETH is not immediately available for exchange selling under Ethereum staking mechanics, so monitoring ETH exchange balances, staking inflows, and spot liquidity is warranted (source: Ethereum.org staking documentation; source: @EmberCN on X). Traders may also watch SBET price action given the claimed association with one of the staking addresses (source: @EmberCN on X).
