I always prefer to hold those coins as the reward received is very less to book profit. I just simply forget about it. Maybe one day, those few tokens will yield me a lot of profit if it is a success.
For the rewards i receive in bounty campaign . I will hold the coin if the price is still low. We just have to check the market price so we always updated,once the price is good that is the time I sell it. I don't mind hold my coin for a long time as long it will profit bigtime once i sell or trade the coin.
