Ukyo sold the coins on an exchange at what he thought was the top of the market back in October. I've posted on the 'Fall of Uyko' thread about this today. He planned to buy back all the coins plus more for himself at a lower price than he sold for. It was a big big gamble with someone elses money.

Right now he has enough FIAT to buy back probably 30% of the coins he sold. If BTC has a major fall he could buy them all back and pay you all back - but that is very very unlikely.

See the 'Fall of Uyko' thread to see how much these shares are worth.

I would say Ukyo is not the best person to be holding these shares right now. If he had control and sold them do you really think you would see any of the coins? Who knows his real identity? He is millions of dollars in debt, possibly going to prison and has all the reasons to run with his ACtM share money.
