Selling of bounty rewards is not a bad option at all for me, but selling all is not good, cause there is a tendency that there will be a rise in the price of the coin. One thing about these projects and their coins is that no one knows which will survive for the long run, which will have a rapid rise in price and if the project's team will keep up with developments. If one is lucky, the coin makes a big profit, those with big rewards enjoys it more, and reverse is the case when the price is goes the other way round.
