i asked in a Greek forum and they told me its ok (but i think they told me only for coinmama) i had chated a lot with that girl...
i hope its just a pyramid and its not a fake site... i also contacted local police station the web crime apartment and they told me there are lot of scamers we cant know each site cause they open and close very quick.... if they ask you money to make a withdrawl its a scam dont pay
The way that I see it is that the "girl" convinced you to buy coins from a legit exchange (coinmama) and then made you send them over to a "fake" exchange, where he/she has full control of. This is the most perfect "coup" since he/she didn't get her/his hands dirty while you did all the work. The web crime department from the police wouldn't be able to help you in this case (I doubt they'll be able to help in other cases) when it's related to crypto because it is very hard to recover this kinds of transactions by force.
Be happy that you came to us now instead of keep pumping money in that exchange (or in buying bitcoins in order to send them to that fake exchange). Consider every money that you've channeled over to this "coin" is lost and will never be recovered. I don't want to feel to hard on you OP, but that's the truth. In any case you should try to withdraw the money of that exchange and see the reactions...
