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 depends on the situation. Most of the time, the moment i get any token from any bounty campaign i immediately sell it specially if it actually reached its cap. While for some instances, you need to allow yourself to be posted on the announcement of the developing team of their plans to make their coins succeed or even just survive. This will help you decide whether to wait if they will induce a pump in the value of their coin or you need to sell the coin immediately.
