I don't think anyone would do this to get Youtube views. Do you know how little Youtube pays people right now. Why do you think so many people are doing sponsorships in youtube videos because the ad revenue is just not too high.
Last time I checked if you got a huge big channel and you get 1,000,000 views you maybe make $2000. So unless this guy got over 50,000,000 views he would only break-even. A few years back Youtube was more profitable but now its very difficult to make any money. Seems like a waste of time these days. Way too saturated even for crypto content.
Obviously it won't be worth the income and expenses if Youtube content is the goal. I don't know what the real reason is either, but I might somewhat agree that it's some sort of tribute from the pope or whoever has most of the bitcoin in his wallet. But for whatever speculation there is, we don't really know what the reason is until the person who sent the bitcoin clarifies it.
Also, the hype about content like this wouldn't last long if those users were actually spending $75K on content alone, but I disagree with why. I tend to think it's either a reward or a mistake on the part of the user.
