According to @EmberCN, a trader known as 波段老哥 has executed a strategic shift from long to short by selling most of his ETH holdings in the morning and borrowing 100 WBTC from Aave, which he then sold for 10.06 million USDT at a price of $100,664. This follows a similar pattern from December where he sold ETH and shorted BTC at $101,482, yielding profits. The move indicates a tactical decision to capitalize on market conditions, potentially affecting WBTC and USDT market dynamics.
