Hey. Yes, you should mention steemit on your videos on youtube and in the description. If you post both here and there, you could actually make all the money you need just from steemit.

See one of Dave's videos. https://steemit.com/@x22report - as an example.

People who are not Dave were posting his stuff for months trying to earn without working. Then Dave, the real one, got on here and made good money for a while. He makes less now because he does not interact with his followers.
