Using a VPN from allowed countries while accessing the site through Metamask would be a practice to avoid account resstriction.
You don't need to only access with Metamask, If using VPN

VPN to avoid country restriction.
Metamask to connect to the platform and withdraw directly to wallet. My thinking was players outside the allowed jurisdiction could easily play and withdraw their winnings unless livecasino withdrawals are reviewed and released manually.
If withdrawals are automated then it wouldnt be a problem but if its manually processed then it would not really be that appealing.Usually a site that do involves with direct wallet log in is something in talks about decentralized stuffs but this one is different which i do presume that transactions would be processed automatically in both ways.
If that member can not access the site, I suggest they not try to visit and register on their site because that can give them trouble in the future, especially if the site does not allow a connection from VPN or our country is on their blacklist. If the withdrawals are manually processed, it will take a long time to process and I do not think that the members will want to wait for that long.
Anyway, for those who will deposit make sure you read their min deposit in btc as 0.001 BTC.
Because if it is less than that amount, it will be void. You can see it from their terms and conditions - deposits.
A common terms but their min. deposit is a bit high if its fixed on 0.001.. Its currently $37 at the moment.
Hopefully, they can decrease the minimum deposit to $3-$10 so we can deposit and try playing some gambling games on their site.
