Sorry to say but this looks like just another scam platform, especially considering the way you were approached and talked into investing.

First of all, girl contacting you through dating platform (in this case Tinder) is their standard practice. First they say that they just want to be your friend etc but sooner or later conversation will turn to investment opportunity which you can't miss, as in your case.

2nd, they are showing of with some big numbers, considering the fact that their domain is only 1 month old



And here are their numbers, that seem inflated and fake, just to attract new users




If I am you, i wouldn't invest anything else that you already did, no matter what they say to you.
