In reading the new NPR report of more Silk Road arrests, this pops out:
Britain's National Crime Agency said it had seized millions of pounds (dollars) worth of bitcoins, the electronic currency used on the site, and the agency's director general, Keith Bristow, said in a statement that other online drug dealers should expect a knock on their door.
So looks like the UK is building it's own stash of seized Bitcoins. Wow. Governments may get their bitcoins without ever needing to buy them!
