In a bull market, only 20% of people can really make money, which is the so-called 80/20 rule.

For every valuable coin and potential coin, there are very few people who can hold it all the time.

In an upward trend, some people do swing trading and cannot get it back after selling; some people play contracts and lose their principal due to liquidation. These are all very common situations.

For ordinary people, you can't be clever, you must have patience and perseverance to be the minority of 20%.
