Making contracts is actually like strategizing in battle; having a systematic investment approach is the key to achieving stable victories, rather than relying solely on luck to become wealthy all of a sudden.

Today, I will share some practical experiences of making contracts with my buddies:

First, when you make money, you need to protect your profits. For example, if you buy a coin and it rises by more than 10%, you need to be careful. If it later falls back to your purchase price, sell it immediately without hesitation.
If you earn 20%, then you must set a rule for yourself that this time the profit cannot be less than 10% before selling, unless you can be sure this is a temporary high point; otherwise, don’t sell easily. The same principle applies: if you earn 30%, then you must at least protect 15% of the profit before selling. In this way, even if you lack the technical judgment for high points, you can still let the profits roll in.

Second, if you are losing money, you must cut your losses decisively. When you buy a coin, if it loses 15% (this number can be set by you, but 15% is a suitable reference), then you should quickly cut your losses and leave. This is to stop the loss in time and not let yourself get deeper into trouble. If it rises later, that's okay; it means you chose the wrong entry point this time, which is a mistake in trading. Mistakes come with a cost, which is a loss. You must remember to set a stop-loss for every trade; this is a necessary condition for trading coins.

Third, if the coin you sold drops, you need to buy it back at the original price. If you sell a coin and it drops, but you are still optimistic about it, then buy back the same amount of coins. This way, the number of coins you hold remains unchanged, but you have more funds on hand. If you don't buy back after selling and the price doesn't drop much, then later it rises back to your selling price, you will have to unconditionally buy it back.

Although this approach may waste some transaction fees, it can avoid a lot of missed opportunities. This principle can be combined with the stop-loss principle, which means buying back when the price returns to the original value, and stopping losses if it drops again. If you operate this way multiple times and find that the price of this coin is always unstable, then you need to choose a new entry point.

In short, short-term trading of cryptocurrencies must adhere to principles; quick entry and exit do not mean blindly messing around, chasing hot trends does not mean recklessly crashing, taking profits does not mean being timid, and staying in cash and observing does not mean exiting the crypto space. Don't get too hung up on the lowest and highest prices for buy and sell points.

It is difficult to support with a single tree; advancing alone is not as good as following the large troop! The direction has already been indicated; it depends on whether you can keep up!
