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
there are some bounty does not pay for bounty participants and then turned to a scam ICOs.
if i already get the tokens, i will sell my tokens once they listed on the market.
if the project looks promising for me, i will hold that tokens.
