I don't think they are the first because as far as I remember LBRY is also offering a decentralized video hosting, I could be wrong please correct me, but I like the fact you reward users for their activity on the site, I've also read the interview with the team and you guys seem really passionate and are willing to work so hard for this project and that's a plus because behind every successful ico is a strong team. Goodluck on this project and I'll keep my eye on this thread for future updates!
If we talk about the concept that TOP developers offer, then this is really the first in the world. Thanks for the support!
