Recently, I saw several friends playing recklessly and losing a lot of money. It feels like the principle is long-lasting, but very few can truly adhere to it; otherwise, everyone would be able to make consistent profits, which goes against human nature and rules.

Many common sense notions in the cryptocurrency world are also obviously evident, but many people think they "definitely can succeed."

1. Very few can continuously make profits from trading contracts, so most people should not engage in it. It's best not to play at all.

If you think you are part of that small group, you should first test with a small investment. You should also see if you can withstand the amplified human nature of high leverage?

2. During poor market conditions, trade less, and if you do trade, lower your position. There are very few assets worth heavily investing in.

3. If a strategy has clearly failed over a period of time, you should stop immediately, instead of continuing to play recklessly.

Strategies have a time sensitivity; different strategies suit different market conditions. The methods for different chains also vary.

4. Do not put all your money in one place, even if it is a top exchange. The occurrence of a black swan event is always something you cannot predict; do not create a story where you make yourself rich again. While the ups and downs of the plot are certainly exciting, many people do not have the fate to be the protagonist.
