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
Real life application and usability of the said token will greatly affect the price, just because it is traded in few exchanges does not mean people need it. Many of the trades are done by bots so they just randomly chose tokens/coins that reach a certain price according to the bot configuration.
If you expect to see a rise in price, consider checking out the real world applications of the token and see if it has potential that when it is marketed properly - people will see the benefits and buy them.
Your bounty token could either be sell or hold. My suggestion for your token to become profitable is to hold it especially when the price is low and when the market satifies you with price then sell. Thats how you do with your tokens. And if you want to make more money you should take the risk of investment.
