in plain view the youtuber really benefits from the existence of video campaigns on the youtube platform but because many ICOs are scam, sometimes their work becomes futile. and just wasting time. therefore the income of the youtuber is not too significant
That is true and with that they will just get more profit the more views and subscribers they get unless that youtuber really is into cryptocurrency or even advocating it. Also what I think should be the projects target is not youtubers entirely but the entire content creator market which is more vast than youtube alone as it can be derived form many platform.
