I'm talking about regular people, people with lack of knowledge. Casino owners are not like them. They are either educated themselves or have educated advisers, so they are not afraid of Bitcoin, but they must take into account the views of their customers
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?
The vast majority of Las Vegas visitors are middle-class customers, and although some of them still can be well educated, most of them are definitely not.
Yet I think you are absolutely right regarding the new rich. Folks from the crypto community will be joining the multi-millionaire squad with increasing pace, and casino operators should definitely take that into account.
