Oh, I almost forget, it pays to be a YouTuber, you need a niche to talk about per se, and it's very easy to talk about a project even if they are going to ruin your life, the secret behind this people is you, the only ways crypto YouTuber makes money is shilling their crypto bags and waiting for new buyers, it's two ways to make money for them, YOUTUBE and CRYPTO BAG..
Most of the youtuber gain money from their content profit and not with their crypto bags. They are just using the crypto content to attract viewers since thats what most people want to watch and not the boring 1hr video explanation about proper investment.
Their content is obviously dont have any good advise for investment purposes but only for entertainment to let the viewers hook on their content. I dont see anything wrong with these since youtube is not an educational platform so content creator can post whatever they want to entertain all viewers since that platform is a social media.
