Tokens from bounty campaigns and aridrops better to hold to the end because you will get nothing by selling everything right away at the beggining but have an opportunity to get more in future.
in general, the situation is quite different. And here we need to approach the situation in a balanced way. indeed some coins after six months or a year can not only double their price, but also rise higher. And there is a situation where coins can be sold at the price of a company after distribution of tokens, because in the future the price will only fall.
