About this, you said he can able to login on bitcasino from outside belgium, do you mean we are allowed to use VPN to access your site?
Of course you can access your account using a VPN as long as it's not suspicious, indeed this is only a limitation from a certain country so inevitably there must be a VPN used to access this site.
Karl said that if you access outside Belgium, you will welcome it, which means that it is clear that you can use a VPN.
Don't think he mean that since for what I understand he mentioned about he can access his account when you are outside on belgium so using vpn while you are in that country is so risky. Maybe you should follow what the law restrict you or else you might possibly get a problem on your account or while playing.
