The rewards from bounty projects will not really reflects how good or not the bounty platforms are presented , but mostly bounty projects has a very good platforms , because they are selling their tokens , but in the end of the bounty campaign there you can see the difference between those bounty projects ,with those good platforms, some are lucky and others are not , so if you pick a good bounty  then its good ,if you pick an unlucky bounty campaign then try your best the next time.
