agreed. in fact, i have been suspecting for a while now that the volatility in btc pricing (which keeps people away, as who wants a currency that can swing +-20% in a day?) might be due to the government using their seized SilkRoad wallet (and whatever other seized bitcoins they have) to overwhelm the market.
people have rallied around the fact that you can't 'short' bitcoins to artificially manipulate it lower - but if you own hundreds of millions of dollars of seized bitcoins (never mind mining for new one), and don't care about preserving the value of your holdings, you could crater the market whenever you feel like it.
maybe im off about the ability to push btc prices down dramatically by say, indiscriminantly selling say, $1-2 million worth? i don't know how deep the market is.. maybe someone here does.
