The way YouTube has been demonitising content for the last year or so might cause some content creators to start looking for a new platform. Only time will tell if they're willing to switch to dTube. It will be tough for many of them to bring along their viewers. Then again, it would only take a couple of influential content creators. Maybe they can start out by crossposting (posting on YouTube and on dTube).

I don't know much about the technical capabilities of dTube, what bandwidth can it support?
