According to U.Today, citing data from Lookonchain and Arkham, F2Pool co-founder Chun Wang purchased 5,246 ETH over the past two days for approximately $10.78 million, at an average price of around $2,054. He subsequently deposited 3,996 of these ETH into Lido and deposited the resulting wstETH into the Sky ecosystem lending protocol Spark. The 5,246 ETH represents the total amount bought back, while 3,996 ETH is the specific amount deposited into Lido as reported; wstETH can be used as collateral on Spark, though reports did not mention whether any loans have been taken out against it yet.
