Tradenix is a scam, one can not withdraw your money, did you guys sign any papers. I have a lawyer working on my case. I tried withdrawing money and they keep saying I have to sign some documents, which gave me no rights to my money.
The Most easiest exchange I have been using, so even if you have a some problems, support team wiil solve it, and the best thing, is they keep you inform with whats happening in cryptocurrency world, if you ever need to ask anything (even if you think its a dumb question) they will explain it in an easy context for you. A lot of thanks TradeNix.
