Well, the best answer should be no. Because good tokens should be able to go up in value in a couple of months to years. Selling should only be an option when you face something difficult in your life, or should I say an emergency that really needs a huge amount of money that obviously is huge enough for you to sell the tokens you got from a campaign.

Obviously, the above options are only for great tokens that you really believe in and have studied well enough to know that it is a worth-it-to-hold-token. Because if not, then you should really start doing your homework. Because if in a specific token that you have received from a bounty campaign you are having doubts and have too much FUD that are truly logical, you would actually be better off selling it.

But then again, my argument still stands. Every token you have should really be worth holding and not something that would make you stop and think if you would sell it immediately after receiving it or not. So always do your homework pal.

Good luck, and I hope this helps
