How did you come up with these bounties ? i could barely pick good ones over these shit projects here in the forum.Cant even know how many bounty scams i did participate because i dont really have a good time to do researching that is why i always ended up not getting paid ! you are indeed luck to have that profits in just few months here in the forum.
i can say that, at this moment i make new topic about how to participate in bounty, how to find best one, How long you must wait to get paid, and another interesing specifics about bounty! 
if you will intersted you will be able to learn more about bounty when i post it. Maybe you can suggest what ist he best forum time to publicate post to reach more audience, to help all of users who will be interested in bounty?!
