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).
They require a minimum deposit for you to be able to withdraw some funds and some gambling site also requires a minimum wager. This is the scenario if you’re dealing with the real Nitrogen sports site.
If you just won money from their competition then better to ask for their consideration or if you won big then .005btc is reasonable to get that reward. But before you deposit, make sure that the site is not a scam site, to avoid losing that money.
