I don't think there are that many people actually worth following on youtube. Most of the crypto "influencers" on youtube are rehashing articles posted by news outlets such as Coinbase, CCN, Bitcoinist, but phrase it slightly different to make it look like they know what they are talking about. Their only motive is to push for content creation and thus more views, not to provide you with unbiased opinions and whatnot.
Alessio Rastani seems to be somewhat of an exception with how neutral he remains. He also isn't afraid of admitting that he is wrong on previous predictions, which can't be said about most of the other entities trying to do the same. They just bury their previous failed predictions (and there are plenty) under a thick layer of sand and move on to the next one as if nothing happened.
