What youtubers do is shill their altcoins - I try to tell everybody to stay away from paid marketing but few listen.
That's how things go unfortunately. It's the same with cloud mining, where so many members here warn newbies about the risks and how it's NOT profitable, yet they invest in cloud mining anyway.
People need to get burned before they understand that cloud mining is wrong, some times even more than once. I'm glad that the amount of YouTubers shilling coins or platforms has decreased significantly last year.
The bear market made a lot of them delete their content and leave YouTube. I remember having read an article last year where the SEC would do more to combat them, which I very much welcome.
