Hopefully, that will just a temporary and it should fixed immediately. Well, I think that will not be a big problem because as long as members can still access the site, they will keep return to the site and gambling.
I am sure 1Win team will do something and makes their X page open for all people.
As I said, I'm not sure whether the fact that you can't access the respective accounts from certain countries will change relatively quickly. Unfortunately, this is due to rights and laws in the respective country (bans on online gambling, etc.), which restricts access for people from the respective country.
You can of course get around this relatively easily by using a VPN, for example, to create a new account (or trying to access the account with a different IP address). Unfortunately, this is not a permanent solution either!
