To achieve stable profits in a bullish trend, after selecting the right asset and entry point, the key is how to hold onto the profits. My experience is: after opening a long position, lock a short position on rallies. There are three ways to implement this idea.

**First: Full Hedge Lock** — This is a neutral approach, suitable for assets at resistance levels with full hedging. It aims to lock in costs and accumulate cheap chips for the long term.

**Second: Half-Position Lock** — Altcoins are prone to quantitative reversals, so half-position hedging yields the best effect. Even if the price continues to rise, your long position still profits; you can defend on the way down and attack on the way up.

**Third: Over-Position Lock** — First observe the strength of the asset. If the increase over a few days is less than 5%, you can make a large short position.

If the price continues to fall after locking the position, don’t rush to close everything. Closing half to retain chips is enough. Never chase a short position midway. Once profits are confirmed, there are only two options: either add to the short on a rebound or hold the long position firmly.

Honestly, many people lose money because of this. Holding onto a long position unwilling to close, and when a correction occurs, their mentality collapses—regret, anxiety, sunk costs—then they open a short at a profitable position. As a result, they haven't even realized the long profits, but the short position loses again. Conversely, if the long position is solid, short losses don’t matter; emotions stay stable when closing. Without the profits from the long, a short loss makes you hold on stubbornly, starting a vicious cycle. Both longs and shorts earning is the true stability.
