Right now, it has become a de facto standard that the "official" price (USD/BTC) is obtained by looking at the market on Mt. Gox. Even on Bitcoin OTC for example, offers are made in amounts relative to the "current market price" on Mt. Gox.
Mt. Gox acts as a spigot for the Bitcoin economy that spews Liberty Reserve USD since withdrawals from Mt. Gox are sent to your Liberty Reserve account number. However there is no comparable inlet for LRUSD. Today, the average Bitcoin participant cannot easily fund an account on Mt. Gox for which to purchase bitcoins. The options available to these participants are to first buy LRUSD outside of Mt. Gox (takes too long, costs too much) or to wire funds to Mt. Gox (takes too long, costs too much)
Thus there is an imbalance between the supply of one commodity (bitcoins) and the supply of the exchange medium (
When those bitcoin sellers on Mt. Gox chase the buyers, the only remaining potential buyers are those whose accounts still have funds available in their Mt. Gox account. Those remaining have the luxury of being able to sit on lower bids and let the sellers approach. As the result of this, the price falls. It is thus apparent, in my opinion, that the price at Mt. Gox does not necessarily reflect the supply and demand for bitcoins, but instead reflects the supply and demand for
To control the price of all bitcoins, simply buy bitcoins from sellers outside of Mt. Gox, transfer those bitcoins to Mt. Gox, withdraw in LRUSD, hold onto those LRUSDs by not selling, rinse and repeat.
Ironically, this actually becomes a less expensive endeavor over time as once the price on Mt. Gox starts to drop, the price to buy bitcoins outside of Mt. Gox drops because other markets use Mt. Gox's price as their reference.
It would make sense then that the ability to easily control the price provides the opportunity to suppress rapid adoption of Bitcoin as a currency.
This is an easily employable option that needs no legislation and can be accomplished without any brute force attack / internet filtering, etc.
