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
Not all but mostly when token once tradable the price drastically drops and it takes time to recover. Recovering mosly notice when the project usability is functional or ther are some like listing event contest in exchanges. For me it would be better to sell immediately and buy the same token when the price drops will makes more token to hodl for future pump.
