I would consider searching at the coin that I would through my 100.
Think of it like right now in Bitcoin, when it was still back in 10k.
Imagine I bought that time and I waited for it to reach by 20k  and there boom. Goal complete, but wait. This is Bitcoin, so this 20k still feels a bit small for that price surge.
Waited and waited then there boom 40k. It doubled. I am somehow contented to sell right now.

So in conclusion, search the coin first. If it never "potentially" reached a certain peak, then sell at that goal, otherwise think twice first.
