Who do you think are the higher rollers...
Gamblers online at bitcoin casinos.
or
Gamblers that play at physical casinos ?
Finally, why do you think that physical casinos attract more or less people (excluding the fact that bitcoin is not mainstream)
it is obviously the gamblers who play at real physical casinos. you can always see a lot of big whales with a lot of money playing there in games like poker and stuff like that and have fun.
besides online gambling is a new concept that has not yet grown that big, and looking at high rollers in casinos i don't think those numbers are even big compared to real casinos.
