Didn't it give you even a small doubt that from free $18, you won $1,000 on the roulette quickly?

Ok, for let's say, maybe you are lucky to hit that decent amount but how about when they asked you to deposit $300 worth to ETH to activate withdrawals, no questions at all to yourself? And because you are in desperation to withdraw that amount, you fall on the trap and just continue to deposit more. You have a common sense it's just that you became blind that's why it doesn't work.

This is getting serious now. Those scammers behind that shit sites now getting easy decent money to all of their victims. Since there is no way* to found out who's those shit people, the community should try their best to spread the words about this scam.

You can see some of the reported website URL here with the same scheme: https://bitcointalk.org/index.php?topic=5081286.0

These schemes have different website names but the system and interface are exactly the same. Sorry for the loss but you have to accept that you can't get your money back now. Slowly move on and learn from this experience.
