If I believed that the reward token I received from bounty will become profitable in hodling for long term then I am hodling it. But most of the token I received I am selling immeditaely once listed in exchange because it is common that the price is dumping in several reasons, like investors immediately seling their token if they already get a profit and jump to anither ICO and mostly bounty hunters are also selling immediately to convert into fiat specially those making bounty campaign as their source of income.
