I'm just looking for the opinions of others really, there's no right or wrong answer to this question.
What do you do when a coin you're holding suddenly jumps up by like 30% or whatever? do you try to sell at the peak of that spike and buy them back once it's gone back down again? or do you just keep on hodling?
If it goes up quickly I usually sold 50-75% of my portfolio and wait to buy back for possible correction and usually it works but still it depends in market condition just always be vigilant in every action you take to avoid being FOMO.
This may vary depending on the situation. Perhaps there was a news that could be increased more. Or there may be a situation where they all need to be sold. So always behaving the same can cause regret.
