Bitcoin is vulnerable to power outages and internet outages, and long term, it is vulnerable to quantum computer advances.
Side-note, ZeroHedge is an amazing web site if you know how to think for yourself. They post many articles that are political and stupid; but when it comes to finances/economics, they post some material that is absolutely without equal. You have to be able to sort the wheat from the chaff, but if you can, ZH is a really good resource IMO. (That said, the politics on the site often make me want to vomit, and the false and biased reporting that sometimes gets posted can be wretched as noted with some of the examples above).
*edit* here is an example that they just posted. This article is something that you won't see anywhere else likely for a week, and this kind of thing is why I regularly go to ZH:
