Trading cryptocurrencies, it took me eight years to figure out some insights. Today I want to share with you the things that can truly change your returns.

**Key Point 1: Don't mess around with small capital**
For funds below 200,000, never diversify. Focus on one main upward wave opportunity per year, and practice simulated trading during other times. Only use real money once the trend is truly established, because one mistake could mean the end. Honestly, knowledge and mindset are more valuable than the numbers in your account.

**Key Point 2: Learn to adapt**
Long-term and short-term strategies must be combined. Always reserve some cash as ammunition—sell at high points, buy at low points—to keep your position flexible. For short-term trading, only focus on two types of coins: those with high volatility and active trading volume. Avoid coins without hype—they are black holes for funds. Rapid declines and quick rebounds happen fast; slow declines and slow rebounds happen slowly. Rhythm is very important.

Another detail: sell immediately if there's a major positive announcement with a high open the next day, and proactively reduce positions one week before holidays. Preventing unexpected crashes is a necessary lesson to protect your principal.

**Key Point 3: Stop-loss and discipline**
This is the dividing line between winners and losers. Losses must be cut immediately—no exceptions. For short-term trading, I use 15-minute K-line charts with the KDJ indicator to find entry and exit points—simple and straightforward, suitable for most people.

Don’t expect to master all skills at once. Master two or three methods thoroughly; that’s far more effective than learning ten superficial ones. Steady progress is the only way to survive long-term.
