【Trader Eugene: Recent losses from going long on SOL, failure to decisively cut losses and excessive position sizing are the key mistakes leading to the loss】Golden Finance reports that trader Eugene Ng Ah Sio shares a recent trading summary, revealing his significant losses while going long on SOL. After making profits on BTC, Eugene turned to long positions on SOL and its ecosystem, originally setting a moderate risk-reward ratio. However, the price of SOL did not rise as expected, and Eugene failed to cut losses in time, increasing his position when SOL dropped to $200, ultimately leading to a loss of $6.2 million, approximately 10.2% of his total account. He reflected that the failure to decisively cut losses and excessive position sizing were the key mistakes that led to the loss. Fortunately, he ultimately succeeded in compensating for the losses through a series of profitable trades and summarized the importance of avoiding sunk cost thinking.
