Sorry to hear your loses in case you can't get them back.
Did he lose his money on that site? I dont think so, I believe his 0.5btc was from the free bonus during registration and he won some additional mBtc from playing the game. IIRC it was like roulette game, correct me if I'm wrong.
The other info that I know is that once users want to withdraw the winning then the required deposit is 0.01btc. So if he did lose some money in this site, 0.01btc could be the max amount that he lost but still I dont think he made the deposit on suspicious site.
Yeah sorry, I didn’t lose anything. I just so happened to win $2,000 on a $15 bet first try. Hahah
Atleast you only didnt lose much on this site you are saying does not let you withdraw once you actually won a decent amount.
But it will be a lesson to others who are depositing enough of a balance over this amount on the site to be wary and try a withdraw to see if they receive anything or not.
