A friend who made a fortune by speculating in cryptocurrencies told me:

1: Leave when you make a lot of money, take a rest, or travel around the world to relax.

2: If you lose more than 10% in a row, be sure to find out the reason for the loss to avoid getting stuck in the quagmire.

3: If you are doing short-term trading, don't trade if there is any ambiguity. Such opportunities are most likely to lose money.

4: Don't follow up if the increase exceeds 50%. Such opportunities are often traps. It is easy to get stuck when buying.

5: After a continuous surge, don't be jealous of the high volume. It is usually a lure to buy more. Control your emotions and don't buy.

6: Buy low when weak, and buy when strong.

7: Don't add positions if you don't understand the situation and are not 100% sure. It is safe to build positions in batches at low levels.

8: Operate the currency you want to buy in a familiar mode to make risk-free money.

9: Don't do callback transactions below the weekly line to avoid heavy losses from early intervention.
