Looks like you guys are restricting US IPs, any plans to change that?
you can use a VPN or a proxy to avoid getting banned based on your IP
not sure about withdrawals,though,but I don't see any TOS lines about not allowing US gamblers
sadly,there are many casinos that do not allow US customers to play
Primedice,for example,don't allow USA and Australia IP's
If The Us residents are not allowed to play in the casino then I am sure that the withdrawal to them will also be not allowed but as they are doing in bitcoin which is anonymous so any person who will use any proxy will easily withdraw their bitcoins as with bitcoin no one know the location of other.
