Re: Livecasino.io -Welcome to a new crypto friendly casino!!!
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 
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.
It is fine if they are focusing on live games because they can always find players on this niche.
But I don't think you can access this site via metamask?
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.
