I think Cryptsy just had a glitch. More likely, it's just some api failure that was quickly corrected and set right in your account. BigVern has been tweeting today about the auto convert tool and cryptsy points market... they had something weird happen and they've fixed it.
I too logged in today, and Cryptsy flashed me a message that said I bought 200 @.0024, but the transaction wasn't in my list. My order wasn't live, and my bitcoin was added back to my account. A broken api is much more plausible to me than 40k uno laundered.
Out of curiosity, on Cryptexplorer.com I browsed all of the transactions in the blockchain back to 450k, and there's nothing in there that looks suspicious. There is no 40,000 Uno transaction, or anything even comparable. You just couldn't hide a thing like that when there's less than 190k coins. Also no change in the richlist. There's also no previous evidence that Coinex had anywhere close to 40k coins stolen (6k is more like it).
I don't doubt that as UNO's major market Cryptsy probably has 40k uno in wallets; probably their broken autoconvert tool sold off everything instantly and they caught it and set it right.
Cryptsy is a good exchange, and has served uno well. Lets give them the benefit of the doubt; if Big Vern was going to launder 40k uno, he's plenty smart enough to do it without raising such a fuss, and he'd probably contact me offline to get a MUCH better price than 1 satoshi (I'd go as high as 10!

) As it is, nobody lost anything. It all points to a glitch in my book.
Yes, its disappointing because I thought I bought a coin I love at an amazing price, but then, it's already at an amazing price.
