I feel you bro, lots of bounty hunters today got scammed because lots of bounty campaign here in forum are not totally payed their bounty participants. But its a part of being a bounty hunter some of Ico will pay you and  accept that lots of them will not so I suggest you to not expect to much to the campaign that you will going to join for you not to be depress if the ico will not pay you just make it a hobby or just a past time like what im doing.
