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 it's better to hold tokens. If you trust the team then you shouldn't worry about token price and watch them develop and deliver promises from roadmap. On another hand if you don't trust them it's better to sell it as soon as possible. But it's still better if you keep small amount, because the price in future can grow and you can sell it for more.
