Hello. Thank you for all your suggestions and advices.

Regarding the site I'm referring to: Yes, it's the legit Nitrogen Sports website (https://nitrogensports.eu)

Talking about the T&C, they never mentioned it during the contest on their official Twitter. They even have this 'double prize to active players' which is kind of disappointing because what's the sense of doubling the prize of winning participants if they are requiring ALL participants to have at least 0.005BTC deposit in the first place.

Another thing, 0.005BTC is such a huge amount of money right now, that is why I'm somewhat hesitant to do it.

Their customer support representatives are also a bit confusing because different customwr service representatives say different thing to me.
