What kind of returns would satisfy you?
Personally, I’d be thrilled with a 5-10x overall gain, though I do have a few altcoins I’m planning to hold longer, aiming for the possibility of a 30x or even more.
I don't actually have an exact percentage or figures in mind towards deciding on when to sell my alts. But when I see that there's opportunity to sell it when the market is green for those alts I hold then will decide to sell it. I don't want to bag hold alts that's why I always think about doing quick decision and will not consider any possibilities for more pumps since for me profit is profit and I will not get bothered on any potential pumps like what other people say.
But for sure other people have different opinion regarding on this matter since for sure they have their own strategy upon selling their bought alts.
