I am not surprised. I tried using this site before and it was an absolute nightmare. Wouldn't let me withdraw.
This cex.io website is up and running again, it was just a temporarily maintenance service check up
I assume was going on in the back end.
Oh good it is back, i have big money there and keep hearing that the company behind cex.io are most likely scammers, anytime it is down, i say to myself "This is it" lol. Unfortunately, it is my only option for BTC-FIAT trading.
