maybe someone can test it with a VPN proxy server Negeria ( open proxy ). I've tried but have only a proxy of South Africa (Johannes burg). and that does not at least bitstake.info
They probably have to verify your account before gaining access to the trading.
when you create an account then get asked only for an email address and username and password. With a VPN proxy Negeria you have an ip address of Negeria. More can not be verified there I think.
