I'm sorry but why you need to be scared? I'm sure that you already learned a lot from watching youtube videos so it's about time that you practice it yourself. As far as the bans, I don't think that youtube wanted it to be permanent. Perhaps they just wanted to get rid of the bad eggs here and free their system with a lot of scammers. Nothing to be afraid of.
If YouTube will prohibit a crypto content, this will greatly slow down the popularization of crypto and create the opinion that crypto is bad because YouTube does not approve of this. Do you think this will not hurt? I am sure that we should afraid of the ban of the largest media platform
