With Bitcoin interest (and prices) spiking, you might be considering investing in your own little cache of digital currency. But before you set up a Bitcoin wallet, you should think long and hard about who will watch over your digital wealth.

In that study, less popular services were more likely to just disappear than popular exchanges -- but popular exchanges were more likely to suffer security breaches, which have also been blamed for disappearing bitcoins.
Their research supports the anecdotal evidence about the security of various Bitcoin services -- or lack thereof. The forum Bitcoin Talk has a relatively comprehensive list of incidents, but here are a few of the most notable (and costly) stories about investing in Bitcoins going bad.
