How about the more obvious reasons, like the financial "crisis", bailouts, bankers that seems immune to common laws, lying and corrupt politicians, high taxes and duties, concentration of power, expensive transfer of money, secret trade agreements, rigged markets and last but not least, the revolutionary technology that underpins Bitcoin?

For my own part, it is the Bitcoin technology that makes all the hype in the world seem irrelevant.

Also, its not without reason that governments all over the world is rushing to regulate this strange new thing.
