The most fundamental reason is that they cannot control themselves, cannot allocate funds reasonably, do not know how to judge the timing and direction of entry, do not know how to take profits or stop losses, are obsessed with all kinds of news, and some even make contracts based on the speeches of big Vs, and regard the profits brought by the bull and bear trends as their own abilities.
The most important point is that they do not conduct systematic and continuous learning, which causes their level to stagnate and be repeatedly cut down.
Some people learned their lesson and went into spot trading, while some refused to repent and continued to make more mistakes, leading to heavy debts and finally withdrawing in disgrace. This is still considered good.
There are also a very small number of people who work hard and earn a little money a month. They deposit their money as soon as they get their salary, and then all the money goes bankrupt within a few days. After finally enduring the bear market, they have no money in the bull market and have missed many opportunities. Such people should not be called leeks, they are pure waste. They are in the cryptocurrency circle only because the high volatility of the cryptocurrency circle can satisfy his fantasy of getting rich quickly as a waste.
What I said may sound a bit harsh, but it is not really that harsh, because what I said is the truth. You can check yourself and find yourself in the situation. Making mistakes is not scary, what is scary is refusing to repent.
