There is no only one answer to that question. It is different for each coin. Some of them have really high potential and you need to hold them for very long while the others are gonna vanish with time so there is no point in holding them. You just need to have a vision to decide which category your coins are in.
yes agree with your opinion, that each coin has its own potential we only need a mature strategy for the coin can be very meaningful when we've held it for quite a while. for other coins can also be a wind alone and lost because it doesn't have a good price or lose in the competition therefore always have a strategy and a lot of searching for existing knowledge
