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 always hold my tokens, I wait until the price is a little increase .. no matter although only a little, the most important price there is an increase. after that I'll sell them, but sometimes I sell at low prices, because I'm too desperate.
