How did she even found out about them? Was it some "friend" recommending her, or it was Google ads?
I can imagine someone who never used another exchange falling for this quite easily as they simply have no point of reference nor do they know how exchanges work.
I ask myself the same question almost every time I see someone get scammed by something this obvious. Where do they find such bullshit scam sites and not notice anything wrong? Talking to support to get a deposit address to deposit should have been enough to raise some alarms. Obviously, it wasn't. And it's often people with money that get hit hard.
She likely had no experience with cryptocurrency and was invited to join that exchange. My guess because I did not ask details how she was scammed by that exchange. I
could not find dgfinex exchange with search so no or low chance to be scammed if no direct invitation from someone.
She did not have any experience with cryptocurrency exchange, deposits so she did not feel odds by have to asking exchange support staff to get a deposit address.
If the story is true, she had $10.000 to waste but no time to make even the most basic of research to find 50 other exchanges where this wouldn't have happened. And then she considered borrowing an additional $5k they asked to "allow" her to withdraw the funds. Amazing.
The story is true and the amount makes me shocked too. Fortunately for the girl, she did not have $5,000 to deposit it so she went around and asked for loan money. I hope my warning will stop her to lose $5,000 but I don't know what she did after all.
