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?
It all depends on the coin, its fundamentals and its market cap. The coin may still be undervalued if the market is down. Even if it does rise 30% or more. I don't think there is a hard and fast percentage that can be used for every case.
