I'm not the type to pile on but bter is also that exchange that was notorious for holding onto large sums of inbound VTC just for long enough to see their value tank. I had 132 VTC trapped in a black hole for about 24 hours where the transaction was confirmed well above 6 times and yet the site just didn't admit it ever happened. Now, it's happening for yacoin. Do you believe in mass coincidences?
