This may sound harsh but it's either your this greedy that you became blind or just plain dumb to even fall for this clear as sky scam.
You can't possibly find anywhere in the world that gives you a 200% ROI. No one in their right mind would've even considered throwing money on such shady deal. Well, there's nothing you can do about it now but to learn from your mistakes. Trust no one in crypto-world.
