Many bounty campaign give token..often token bounty has not been paid .. you already exist in the market .. after the price paid it down drastically ... if we hold the token .. later will be able to rise or even added down the price of token bounty
I think you should sell it specially now that the market is quite low and keeps on crashing not to mention the increasing number of the bounty campaigns that do not give out rewards it is much safer for you to just sell the tokens you receive right away but on a reasonable value instead of just holding it to just lose further value.
