Are you aware of how many "decentralized video platforms" exist right now? Why on earth would people be interested in what you haven't yet developed when they have Antonio Banderas and Johnny Depp aligning themselves with projects like Tatatu? Unless you have boatloads of money or the next Einstein, your idea won't succeed.
This type of project is needing good amount of money not just in setting it up, getting good people to man the project and then making sure that the project can get on the ground by promoting it to get people to use it. Remember that YouTube was not profitable for many years until such time that it already exploded and establish the name in that industry. Now, if the project can target like a niche and can offer unique selling propositions then why not? Go for it and make a crowdsale for the project...and I am hoping the project can gain some share in an overcrowded market.
That's what I have been thinking as well. What about the competition? How does this platform theoretically differ from the likes of Twitch? Okay yeah, centralization is one, but the way streamers and the platform makes any money is through viewers, how does OP wish to get viewers? What about Play2live, Theta token, Livepeer etc?
