People can never make money beyond your cognition. Even if you make money by luck, you will lose it sooner or later.
Don't touch leverage. Especially don't touch non-mainstream coins. Because non-mainstream coins, as long as there is a trader who uses 20,000 U to smash it, this non-mainstream coin will be completely taken or long. Non-mainstream coin traders have absolute say, and other retail investors are leeks.
After receiving salary or other income, continue to buy when the currency value is low, and hoard mainstream coins by configuring mainstream coins. For example, Bitcoin was still very cheap in 2020, so you need to buy and hoard coins at this time. Wait for it to rise. After it rises, judge the market sentiment and make a move when it is time to make a move. It is said that many people bought it at 30,000 yuan that year, and the market was hot. When it rose to a high of 69,000, many people thought it would continue to rise to 100,000, but the fact is that it has been falling all the way since then.
