Very often, due to the desire to make short-term profits, long-term cryptocurrency holders become hostages to their own desires. They sell assets that they originally wanted to hold for a long time in the hope of buying them back cheaper when prices fall. This can lead to the cryptocurrency market continuing to grow, and instead of having assets that generate profits, they are forced to hold stablecoins, which do not allow them to earn as much profit as volatile assets. In my opinion, the desire for short-term profits and changing one's strategy very often has a negative effect.
Wish they can see the vision. Making money by holding is the best way to move and not a lot of people do that, if they are not careful then we can be very risky by looking at just the short term. That is specially bad when you think of how short term doesn't really end up with anything different for the long term, so it is not really reasonable to expect the same results for these. If you do that, then you will only make short term income, but that's bad.
Even when it's high up, then it would not be smart decision, just keep holding because even if it goes down, then it will go up eventually again and even higher. So, if you sold at 65k at peak last time, you would profit then, but now it is 120k so nearly twice the profit would be lost.
