This thread was created five years ago but it still rings a bell, during the heydays of ICO Youtubers plays a vital role in many ICO projects, I fall on some of these influencers and got burned, this is where I learn to do my own research, your own research means you hear and read all the other reviews and views, especially the cons and bad feedbacks because this is where you get to read and see the weakness of the coin.
Youtubers are great at shilling a project, they always make it appear that the coin they are promoting is the coin you'll looking for or the next Bitcoin in the making.
Once I hear that the coin they are shilling is the next Bitcoin, I just know that this is a paid promotion, a good reviewer should always dwell on the good and the bad side of the coin.
This guy called Suppoman still has videos from years ago, this is one way to know if he is lying all along it not, but I confirmed that he was not trolling around, almost all projects he called in 2018 did amazingly well, he made a lot of money, he called Fantom, Matic, Avalanche and many more, I suggest watching his last year bull market video before judging him, I don't like YouTubers myself but the truth is just there.
