I feel like too many of the Crypto Youtubers have turned into hype machines / Pump n' Dumps. They do superficial analysis of coins (or copy others), buy into them, promote them, get others to promote them, watch the price rise, convince people they're onto to something, and then the process just repeats itself.
My guess is, no other Youtubers are going to say anything negative about XRB since they probably already bought into it and have started the hyping process.
