You are very much welcome aboard but I am sure you will have to take many lessons and must know that bounty programs are not as easy as you are thinking. Most important thing is, I am not demotivating you or something like that but I am trying to tell you facts.

Not all bounty programs will be legit one at the end.
You will find more than 70% bounties becoming scam by the end of their program.
If you encounter such events then you have to be patient and keep finding others.

Best way to follow is :

Divide the campaigns according to the Managers. There some of the good managers who manages almost 90% legit campaigns so find them first and join all their bounties.
