The strategy of doubling and cashing out is actually fine. Establishing a 0.5b position at 32k, successfully taking profits at 65k, and executing well. But the real regret of this trade is—completely clearing the position.

Not leaving a reserve is a fatal flaw. When the token's market cap dropped to 7k, I liquidated 7 million tokens, converting them back to $50. It sounds like a number, but in reality? The opportunity cost of this move is far more than $50—the slippage fee alone might not even be enough to trigger a stop loss to this level.

The key reflection is actually simple: position management is always more important than entry point. Doubling doesn't mean perfection; perfection requires leaving a hand at the top, so that you can gain extra profits during subsequent rebounds or long-term holding. Many people get caught up in small slippage costs but make fatal mistakes in critical liquidation decisions—this $50 loss is essentially an inevitable result of improper position allocation.
