I'm so sorry for the OP for being scammed. "Secure deal feature"? You should have checked the site first. The site is never heard of. No reviews from trustpilot. For sure, the sites involved are interconnected with each other and only one scammer is handling it. Too bad, the OP can't get his money back in this case. Even top exchanges like Binance doesn't require minimum deposit of $500. You should have doubt its motive. Expensive lesson learned by the OP.
Definitely an expensive lesson to learn on my part. I wasn't under any kind of illusions that I'd be able to recover my money, I was just trying to make sure that this site has some kind of negative attention out there. Honestly it was definitely my own fault, I should have done more due dilligence but I got overexcited and ultimately, stupid.
So yeah, don't be like OP (Me), the "benefit of the doubt" usually ends up being the grave you dig yourself.
