According to @EmberCN, prominent crypto trader @qwatio maximized leverage and rolled profits to expand a position to $300 million, but after a mild market rebound, his position was forcefully reduced to $195 million at 9:00, wiping out over $9 million in unrealized gains and lowering floating profit from $11.22 million to just $2 million. This case highlights that aggressive profit-rolling and excessive leverage can lead to rapid liquidation or loss when markets fluctuate, emphasizing the importance of robust risk management for crypto traders.
