On-chain data tracking shows that a trading expert's recent moves are quite impressive. First, they sold 255 BTC, then made a profit of $3.85 million by shorting BTC, ETH, and SOL. This guy clearly has no intention of stopping; he is currently shorting these three assets, with unrealized gains already reaching $1.77 million. It seems he has a strong confidence in his short-term market predictions. Such precise operations with large positions are indeed worth the attention of market participants—whether to validate their own judgments or to study the strategies of professional traders.
