I support @dtube and I think their interface for uploading videos is superior to YouTube's.
If I post a popular video on YouTube, it will continue generating revenue over a long period of time. With DTube, there's only a 7 day window for SBD/STEEM revenues, so I think it's niche will be with current affairs content and vlogs that give updates. Or is there an advertising component that would make it attractive for long-term revenue generation?
