Hello that isnt easy to do actually ans eat probably a lot of youre time and effort. There are so many helpful site like this but youre compilation is good. I am just wondering if you could add aome bounty in altcointalks forum as well I can see they are now doing some campaign and some are good as well. The latest one I saw was the 2 weeks IOTEX campaign that has been paid in eth. That's rare case but I think that forum will soon caught up with bitcointalk forum famousity.
The reality of a bounty company extends to several formulas where you can advertise projects. But in any case, bitcointalk is the most requested and most visited among all users of cryptocurrency.
