What I do is I sell half of my reward i.e if I'm not in need of cash urgently.

That is an unavoidable event, most of the tokens that were in the past were good. But the more shitcoin, then holding it because forced is something that must be done and it's better than we have to sell it at a very low price. Because after all if they are a project and a solid team, then at least they have a strong effort and desire to recover everything along with the recovering crypto market.
