You can control whether to hold or release the coin in the following ways:

If you really cannot understand volume and price, do you not know what constitutes an increase in volume or a decrease in volume? Are you unsure whether the price increase should be classified as large or small? Can you not define whether the coin price is at a high or low position?
1. Sell during a rapid rise (strong breakout period, funds uniformly intervene to raise coin prices, thereby enticing more buyers)
2. During a rapid decline, observe or buy (consistent funds exit, the whale dumps to wash out floating capital, then pick up cheap chips to raise the price)
3. Buy when the price is rising slowly (the market maker lifts and suppresses the coin price simultaneously, causing the coin to show a slow upward trend. This is also a way to clean up floating chips, and once cleaned to a certain extent, it can trigger a rapid surge.)
4. Sell during a slow decline (this is actually an absolute selling process, a dull knife wears down the person).
Note:
1. The above coin trend is based on the judgment of a stable market situation and is not applicable to extreme market crashes or surges.
2. The strong positive and negative news for a coin is also not applicable.
