I don't see anything wrong with posting to Youtube and then making a short post to share it on Steem. When you say, it "isn't worth it"- It only takes a few minutes to share a video on Steemit or Dtube or whatever you use. While I can understand, it could no longer be worth it to make videos specifically for Steem in hopes that the value in Steem will "be worth" the production of the video, I would hope that you still take a few minutes- repost your Youtube video on Steem and collect some crypto- with no expectations for how much. Would just hate to see you go.
