If a 9/11 type terrorist attack was funded by Bitcoin, it would catastrophically change the worlds view of our beloved currency. Sadly it could happen. If it does then lawmakers could pass an anti Bitcoin bill just like they passed an anti 4th amendment bill after 9/11. In the short term, the price could shoot up, as so much publicity would inevitably attract new buyers. However, I would hate to see Bitcoin become known as a terrorist currency.
