So the full story goes like this:
I got a promocode for that site, they have a roulette game, and the code was like for a one round in that game. Well, I won, totally over 2000$ in btc, eth and bch. In order to cash those, the support said I needed to make a minimum deposit, like 0.013 btc.
Yeah, we've heard your story unfortunately from tens if not hundreds of users.
The same scam, they offer you bonus codes, the games are rigged so you surprisingly win, but in order to get your winning, you have to make a real deposit. And then you win more, and you have to deposit more. And then you have to play more and you win more...you get the idea!
I have thought like what they do with my money, I have deposited so little? What it is worth for site owners to rob my money. I guess they could go for bigger amounts with somebody else, I am just a ordinary guy with minor funds?
You deposited 0.2 BTC, in a lot of countries that's 3 to 6 monthly wages, it costs them 10$ the domain and 5$ the hosting.
Quite profitable, isn't it?
Bottom line.
Never , NEVER! deposit any money on a website that ask you for $ in order to withdraw your winning.
If they are legit they would take that sum out of the winning, right?
