The difficulties of purchasing bitcoin are not the fault of Bitcoin.
There are numerous possibilities regarding the
BTC holdings of the "Winklevii". One is simply that they are lying. Unless they expressly
prove they own the bitcoin they claim to own by means of signed messages using their private keys, we'll never know for sure. Maybe they bought the 'coin on Trade Hill. Maybe they run their own Avalon ASIC farm. We just don't know.
