Don't be greedy in the currency circle, remember the following investment principles!

1. **Replenishment is to reduce losses, not for huge profits**: When you are stuck, don't fantasize about rebounding, just think about how to reduce losses.

2. **Calm market is often a precursor to big fluctuations**: Don't be confused by the stability in front of you, and be prepared to meet market changes at any time.

3. **There must be a callback after a big rise**: Be vigilant about the triangle pattern, and don't chase the rise at a high level.

4. **Buy Yinxian and sell Yangxian**: Enter the market when the market is panic, and withdraw when it is crazy. This is the operation method of masters.

5. **Don't sell when it goes high, don't buy when it doesn't dive**: Don't act easily when it is sideways to avoid unnecessary risks.

6. **Look at the pressure level for the rise and the support level for the fall**: Know the market trend and make arrangements in advance.

7. **Full position operation is a taboo**: The currency market changes rapidly, and it is very important to maintain the flexibility of positions.

8. **The most important thing when trading cryptocurrencies is your mentality**: Greed and fear are your biggest enemies. Only by staying calm can you be at ease in the market.
