In my opinion yobit pays the best they have a very good system of updating their members earnings and you can cash out your earnings from the campaign yo your yobit wallet and from your yobit wallet to your bitcoin wallet..
I think the system is great and hassle free for campaign managers and posters
Yep. I tried other signature campaigns. But Yobit, other than it paying decent, seems to be the most stable ever there is. You should try Yobit.
