Agree with you on both points. because of limited payout time I would't leave youtube . My content also have different age group compare to Steemit (art for kids) . Making videos exclusivly for Steemit is to risky for me, because it take 6-7 hour to shoot and edit for only 1 week of a pay. On youtube my videos can do bad in the beginning but go up to the stars in a few month.
