The fundamental reason why ordinary people lose money in cryptocurrency trading:

The reason 90% of ordinary investors lose money is: small positions during uptrends, large positions during downturns.

The reason for this is a matter of trading habits.

When buying a rising cryptocurrency, most people do not take large positions, and then, because of the continuous rise, they cannot resist the temptation and keep adding to their positions, ultimately getting caught in the pullback moment. As a result, small positions make a profit while large positions lose significantly, although there are times when they might add correctly. However, trading cryptocurrencies is a long-term endeavor, and this kind of trading habit will eventually lead to significant losses.

To avoid bad habits, one should develop a habit of selling high and buying low, not the other way around.

First: Maintain fixed position sizes and avoid random sizing.

Second: Once positions are established, only reduce positions, do not add more.

Third: Avoid randomly entering positions, especially during unclear market conditions.

Advice for ordinary investors: "Experts" are just a cut above.
