have seen is big confusion on this topic
Is important to understand that there can be bitcoin (and we talk about bitcoin only) at moment to be regulated in some of the countries around world
then is a ethereum, neo , dogde so on....
after that... the regulation is mostly for tax issue....
who pays tax if i have hold casino in bitcoin where country has bitcoin as money, all players or only players that is in that country?
At moment for BITCOIN casino,
if you host in a country where the bitcoin is officially considered as money, you have to check the laws....
Bitcoin has no names... could be considered 100% anonymous
All players could bet from a country that doesn't reconize bitcoin as money...
Casino could have multiple server that host it in different countries
For none bitcoin casino
Every other crypto it could be considered token or playmoney
because there is no exchange of money
no deposit with FIAT currencies
no cashout FIAT currencies
no transaction between FIAT currency or other currencies
so at moment if a casino use AZ or XY coins/token doesn't need geo license
It could have a gambling trusted agencies license for control of the right execution of the website
control that is nothing against the end user.
PS: Anyway even if i would be in Spain and I use Bitcoin + vpn... nobody could catch me
