They are scamming selectively. They don't scam small fish, but once you get a bigger withdrawal, they will take it. After all, why wouldn't they? They are registered in offshore and there is nothing you can do about it.
Do you have any evidence for this? You said ''They stole all the users funds and exit scammed with quite a lot of money.'' ''all the users funds'' Now you are saying only a few users? Did they scam you? Their website is online now, have you tried withdrawing?
