Well, I wouldn't call those dudes "regular people"
I refer to the strata of society that frequents Las Vegas-style casinos ("crème de la crème"). They are definitely well educated and we should expect more Bitcoin supporters among them than among the regular crowd. I wouldn't actually be surprised if many of the nouveaux riches turned out to be the new rich specifically because of and thanks to Bitcoin. This is what casino operators must take into account as well
I agree with you on "crème de la crème" that most of them are well educated, but these people do not make up the majority of Las Vegas visitors. Take a look at the stats:
Number of visitors to Las Vegas in the United States from 2000 to 2018 (in millions)
I presume that over 90% of those 40 million are not "crème de la crème", don't you think?
Was it Mark Twain who said that there are three kinds of lies?
Namely, lies, damned lies, and statistics. And since the intensity seems to be rising from left to right, we must assume that statistics are the most insidious and treacherous form of lies, even more damned than the most damned of all lies. More specifically, we don't know how unique these visitors are at all
As with online gamblers, there should be gambling addicts as well who spend their whole days, or rather nights (or maybe even days and nights), at the tables. In this way, we should be very cautious to draw any definitive conclusions from these figures as to who actually visits these establishments and how often
In fact, I heard that narrative many years ago, that the majority of money comes from simple folks. But that must be an urban legend, myth, or something to that effect
New money versus old money
