After entering the crypto world, many people get stuck on two questions: with so many coins, how do I choose? With such frequent price fluctuations, when should I buy in and when should I sell out?

Actually, there's no need to complicate things. My approach to selecting coins is very clear: it revolves around a few strict rules, aiming to reduce mistakes rather than chasing hot topics every day.

**Step 1: Narrow down the selection range**

I only look at coins with the most obvious recent volatility and sudden increases in trading volume each day. Those with poor liquidity, no matter how good their trend looks, I avoid. Coins without institutional participation generally won't have lasting trends, so watching them is just a waste of time.

**Step 2: Use long-term charts to determine the trend**

Short-term rises and falls can easily mislead you. The truly reliable reference is the long-term chart. When monthly indicators show signs of strengthening, it indicates a trend is forming. Following the trend at this point is much more comfortable than fighting against it.

**Step 3: Wait for a pullback before acting**

Once the trend is clear, don't chase highs. Learn to be patient and wait until the price returns near important moving averages before taking action. If the price stabilizes and trading volume begins to increase, it indicates big funds are entering. This is a good time to buy in, as risks and costs can be better controlled.

**Step 4: Discipline over subjective feelings**

As long as the price holds key levels, hold according to your plan. If it breaks through effectively, exit immediately—don't care whether you're in profit or loss. The mindset of expecting a rebound often leads to bigger losses. Strict stop-loss is necessary to make room for future opportunities.

**Step 5: Take profits in stages**

When the price rises to a certain level, sell part of your holdings first, keeping control of the initiative. Use the profits already made to bear the remaining risk. This approach makes your mindset much more relaxed and your operations more stable.

**Final thoughts**

In the crypto market, the real difference isn't who has the sharpest vision, but who executes most steadily. The rules seem simple, but very few can stick to them long-term. As long as you maintain this rhythm, you'll naturally make fewer mistakes. The recent volatility of coins like MET, BERA, and RONIN is worth paying attention to. The market brewing process is underway. Keep the rhythm, find your suitable entry points, and the next opportunity is right in front of you.
