Why can't you always hold onto your coins? There are two key reasons:

First, there is a lack of patience.
Market fluctuations are washing out positions, many people lack determination, they rush to exit when there is profit, and want to cut losses when they are in the red. Frequent trading leads to missing out on real uptrends, and they only regret it when the coin price has skyrocketed.

The second is improper position management.
Using money you can't afford to lose to trade coins, heavily investing or going all in, once the trend doesn't meet expectations, you panic and naturally can't hold on.

To solve this problem, you need to invest spare money, maintain a calm mindset, and not let it affect your life, so that you can truly hold on and be stable.
