As just a consumer I dont really know how time consuming it is to just post on both plattforms. ( I imagine you still want to interact with your followers on every platform and maybe other things I am unaware of)

But I think it will take a while tbh.
Crypto is still new or even unknow to most people and how it can be so valuable.
I think the first question you have to answer is : Who is paying me? How does this work without ads? How or why should I trust in this? How easy can I cash out? etc
Also I mean look where most of the videos going around here are stored.

As far as I know steem is also working on a video platform, when/if this gets out it is another story.
