Marc is absolutely right. I've been a high tech entrepreneur for 40 years, and the trends I'm seeing in the virtual currency space remind me of other major disruptions: the Internet, the worldwide web, Google, etc. Economists who predict the demise of bitcoin focus in on one or two properties. But bitcoin is much more than a few characteristics. When the Internet was born, nobody had conceived of the killer app, world wide web. The same is happening with the birth of virtual currencies. Milton Friedman actually predicted the rise of virtual currencies in 1999.
