You said that you have invested your money, right?
Why you just ask about the fake site or not now?
The question should be asked before you invested money, mate. So, if you just realize one of the sites is fake, you are too late. For the next time, don't do it again, make sure everything first before you invest your money.

By the way, why you are too confident to trust the girl. You just know her through the tinder app, don't you? Don't be so easy to trust a person that you just know. Especially a person who offers you a crypto investment with unrealistic profits. That's a classic way done by scammers.
