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?
Sadly cryptsy does the same thing, they say they "add more servers" to fix that sort of thing or that it's just waiting for network confirmations but I call it a scam. Happened with doge I only got my coins after the price crashed once. Took like 6 hours to get my deposit there.
I think that markets in some exchanges are heavily manipulated. That's why some coins will be going so high, as there is no supply and the market will increase artificially.
Finally I see my 1500 yacoin in bter.com now !
Glad to see this.
Hopefully I can withdraw the BTC though.
