It's more than that in my opinion.  Even the GPU mining youtubers probably were earning more money through YT itself as well as sponsors and whatever else than they were by mining.  It's funny to see ones like Voskcoin and others try to keep their channels relevant now that nothing is profitable, because some of them have zero speaking skills and no interesting content to create anymore.

Bitboy crypto is the worst, tho.  You look at him and see how many followers he has and that should tell you how so many people got scammed by FTX, which no one should have kept coins on in the first place.
