Is x-grape.io a legitimate exchange? I met someone who keeps encouraging me to sign up there. Never heard of it before and can't seem to find any reviews. I was able to register with an invitation code but haven't provided any personal information yet.
if you are in doubt, better to just avoid it. it's not worth risking your personal information or your money(if you ever decided to deposit in it) on an exchange that almost no one knows about. also, the fact that the person you met keeps insisting that you register is suspicious.
