In actual we can say surely that which is guinine or not but still if we can take some attention over few things then we can make sure thst whether the bounty program is guinine or not .
First of all see at the manager of the campaign whether he is high ranked memer or not or he has positive trust or not , this will clearly indicate whether the bounty program is good or not .
And beside these factors you can see over the amount of the bitcoin or another tokens that they hold to distribute to the participants of the campaign .
And another factor that is are they paying weekly or not , if they are not going to pay weekly then there are chances that they may scam because once happened with me , I remembered very well .
