play? no you cant play them because bounties arent games that children plays. bounties are infact risky and not fun at all because your quality time and hardwork is at risk here because you cant assure and guarantee that they will pay you for your effort because majority of bounty campaigns are mostly scam. so overall i suggest to you is read all their important infos like whitepapers , ther websites and their teams behind them if they are legit or not although it is really hard to tell if the ico bounty is a scam or not.
