This is a screenshot of the platform view through my phone.


Quoting this for visibility.

I presume your friend hadn’t tried to perform a withdrawal from the platform before passing it on to you as a recommendation, and therefore was not aware of the whole scam sequence.
I was also thinking this and perhaps his friend did not withdraw also, and experienced the same as OP.
Only scam exchanges ask deposit when it comes to withdrawal, I suspect that this friend OP said is also behind on this scene or a scammer.
