Did I miss something? Bernanke's comment basically boils down to "no comment", phrased in the polite speech Senate committee hearings. What's the news here?
The news is that the government isn't likely going to throw a shitfit and freak out over bitcoin. Because it's money related, and they can tax and regulate some piece of the transaction.
Doesn't really need to be said that Wall Street, Washington, and Lobbyists are all in bed together. Wall Street types and some Valley people have clearly told influential politicians in this that they should be cool.
Bitcoin gets another serious mark in the de-risk column
The Fed is not the government (its a private bank btw), and Bernanke's comments do not apply to agencies for which virtual currencies are their jurisdiction.
