You've been scammed people, face it. I've been waiting to see this exit scam since Coinsmarkets started. Back then someone on this forum rang the registered telephone number and got some old Dutch lady who knew nothing of cryptos or Coinsmarkets. With this in mind I never had more than 0.05 BTC in there and never for long.
We had been warned. If people just believed that person who did that lil background check of calling that number.
My first impression on this exchange was really not that good.
The interface is not user-friendly and even the pairings are not well organized.
But I used it several times as there were some coins traded only on this exchange.
And yes, good thing that I never stored btc for so long on them.
And now, their website is totally down!
