If all these bitcoins stored on MyBitcoin are in fact gone, does the price of bitcoins go up due to a lowered supply, or down due to a lack of confidence infused into the market?
I wondered myself if it was an attempt at market manipulation, but I think the only way it would drive the price up is if the market was in a rapid downturn - that is, confidence was already so low that only freezing accounts would stop people from selling off their coins.
