Bitcoin may or may not become a historic digital currency. But either way it heralds a paradigm shift in the way we think about money. Bitcoins aren’t a national currency. They’re not associated with a mint, regulated by governments or banks, and they’re traded digitally–without any real “item” changing hands, even something as transitory as a credit card being handed over to a salesperson.
