I think you should not make your post confusing or hasty in making a conclusion.  The bounty campaigns that you posted are still ongoing hence you cannot say that you earned the said money already.  What you have are just potential earnings (hoping that all of them are not scams and will pay you right). 

As my opinion and recommendation to newbies, always do research prior engaging to the bounty campaigns to avoid being scammed.  Moreover, even if you are already part of it, researching during the bounty campaigns is beneficial to you to learn more about the project and to further strengthen your resolve that the campaign is not a scam (or if they already issued the coins, researching will help you decide if you will hold onto to wait to increase in value).
