H O L Y SHIT! This is definitely new.

"Bitcoin trading is probably susceptible to irrational (or rational) bubbles or loss of confidence, which could collapse demand relative to supply. For example, confidence might collapse in Bitcoin because of unexpected changes imposed by the software developers or others, a government crackdown, the creation of superior competing alternative currencies, or a deflationary or inflationary spiral. Confidence might also collapse because of technical problems: if the anonymity of the system is compromised, if money is lost or stolen, or if hackers or governments are able to prevent any transactions from settling."
