WE GOT CASH TRADE ROOM TEY ADDED IT HOLY pomegranate

My opinion on that is that nexon did a bad copy paste from kms and left the nx trade system implemented

No. There has already been a point where cash trade was added before, it was in Korean, and iirc didn't work(like this one). It had to be opened with like '/tradecash' or something.
This one, however, is translated, and has a button when right clicking to use it.
