Token bounty for me must hold because it has no value if sell it now. My efforts are useless because token value now are very low. But even though that's the case now l trust that in the future my tokens will turn to millions.
Actually it depends on the token, it can not be generalized. There are projects that are well developed so that when listing in the market the price is very high, some of the development is slow, and some are declining all the time. So, you should always update the latest information related to the token. But the last thing that often happens is the token price falls after listing, it becomes a dilemma.
