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
In my own opinion, it depends on how much the price of the bounty token you have earn because not every cryptocurrency in the market does have the potential to grow in the market since every coin will only grow if it has a good platform.
