You know I had a mad theory about this.
Imagine the Govt just decided to buy a huge amount of Bitcoin. I mean they could just print the money right?
Anyway, if the Govt, or anyone, owned so much of Bitcoin, then presumably they would have some influence/power over the price.
But all Satoshi would have to do to destroy that hold, woul be to dump his bitcoin onto the market, the price would fall dramatically, and the Govt, or whoever, would lose a fortune. As long a satoshi´s Bitcoin is tied up, this would always be a threat.
