Does anyone here still plays in Nitrogen Sports? Did you ever tried depositing in their site?
I have a balance in there, but they require me to deposit 0.005BTC first before I can withdraw the balance (which I won from their NitroSpread contest promotion).
https://blog.nitrogensports.eu/squares/rules/You can read the terms of their contest in that link but it seems they are asking to deposit for the first time depositors so if you already having balance means you are not a new one then why the hell they are asking to deposit?
