Investing in the crypto world, the biggest fear is rushing. Rushing to buy can get you trapped, rushing to sell can cause you to miss out. These two "rushes" can ruin more than half of your wallet. True experts understand one principle: stay calm when buying, be decisive when selling, and as for stop-loss—never delay, not even for a second.

Many people like to scatter their funds into many small parts, but the result is often being overwhelmed from all sides. In fact, the most prudent approach is exactly the opposite—concentrate your firepower on selecting good projects, always leave enough reserve funds for yourself, never fully commit is a golden rule, and riding the trend is an iron law. During small dips, add small amounts to test the waters; during large dips, that’s the real opportunity. Correspondingly, small rises and small sells, big rises and big sells, and during explosive surges, sell everything immediately—timing is crucial.

There’s a saying: opportunities are created by dips, while risks come from rises.

In practical operations, the same action can have completely different effects at different times. A big drop in the morning? Add to your position. A big rise in the morning? Reduce your holdings. By the afternoon, as long as the price is pushed higher, it’s time to reduce. If there’s a real crash, it’s better to wait until the next day to re-enter. Don’t rush to sell during morning dips; adding on dips for T+0 trading can be more flexible. In the afternoon, don’t chase after the rally; controlling the rhythm and using T+1 rolling operations is the best strategy. Another detail: whether a coin can continue to strengthen can be predicted by whether it peaks at 10 or 2 o’clock. Strong coins tend to top out at 10, while weak coins can’t hold until 2 and need to turn back.

In a bull market, don’t do reckless short-term trading; in a bear market, don’t chase long positions. When the bull market arrives, don’t panic sell; when the bear market comes, never chase the rise. This is the lesson the market teaches everyone.

To sum up in six sentences: buying relies on patience and gradual layout; selling depends on decisiveness and quick profit-taking; holding coins relies on confidence and endurance. During upward trends, small dips are good opportunities to buy; during downward trends, small rises are better to sell. Building positions gradually allows for longer survival; going all-in often results in losses. Support levels that are held for too long will inevitably break; resistance levels that are attacked repeatedly will eventually be broken. Shorts can make money, longs can also profit; those who lose money are often the greedy ones. The most straightforward advice: eat until you’re about 80% full, and when you’ve earned about 80% profit, it’s time to run.
