I do not have a clue who you are, what your interest are, or what your youtube channel was ever about. Not everyone on steemit were fans of youtube or facebook. If you want you audience to grow on steemit, provide a little background. If you are a live streamer check out d-live. Just pulling your content from you tube and posting it here on steemit could have adverse actions, so make sure you indicate that the work is yours and link your accounts, this will avoid @cheetah bot flags for plagiarism, and wasting the time of #steemcleaners doing a follow-up.
In closing if you are happy with only your same old fan base and do not want to grow then not letting new users to steemit know what you are about is a good way have a stagnant fan base. If you need help there are a lot of places to get it, you just have to look. Or if I can help I will try.
...he does have over 200,000 followers on you tube....
He could take a couple of minutes to say what the video is about, or do an introductory post, this is me, this is what I do kind of thing. Maybe he will oneday.
