They want another deposit in order to enable withdrawals. This was final straw for me, this seems totally sketch.
Yeah, well it's a good thing you realized it now and not later, after you would have sent them more funds that you'd likely never have seen again. Asking for money in order to withdraw is probably in the top ten methods scammers have (with variations on the theme) and use most frequently.
Tinder is notorious for being a hangout of scammers offering trading return more than George Soros. I even think that there really isn't a girl on the platform.
Lol. I'm not into social media sites or whatever it is that Tinder has to offer, so I've never visited their site or used the app, but I'd bet money that you're correct that the "girls" on there (at least the ones who are apparently giving out links to crypto exchanges) are really humans with dickandballs, XY chromosomes, bearded faces, and yada yada. Guaranteed.
OP, if you're going to use crypto exchanges, don't fall for these tricks. I don't know how old you are, but you really ought to know better than this.
