It is a proof that fiat based poker site is still popular compared to crypto poker sites.
The same we can say about any type of crypto activity compared to offline counterpart. Maybe except drug selling

I have no idea why the traffic of crypto poker sites is not able to increase or at least compete with fiat poker site.
Traffic could increase, but there is no such poker crypto sites. And this is weird. There a lot of slots and dice plus crypto books, but there is no good poker lounge.
