Nitrogen blocked my country IP and ask to send them an email and contact them in order to make an exception and to log in with my country IP.

As for sportsbet I know I can safely deposit and safely withdraw up to 0.10 btc without the need for KYC, above this amount they can ask for KYC but maybe they don't. Anyway I like their cashout options just like bet365 and so far never had any problem with them.
