Is the taxi driver on Facebook, using Google, or tapping on an iPhone? Is he using Uber to drive passengers to their AirBnB from the airport they just flew into after booking a trip on Hipmunk? If the taxi driver is aware of it, it must be a bubble.<p>Over the last five years the people shorting governments/mortgages/banks, buying into gold/tech, and predicting a coming total collapse have in general made an ungodly amount of money.<p>Is Bitcoin's rise assured? No. But if it was then there would be no gain, no upside. There is a certain kind of person, all too common in our managed and enervated society, who does not know how to take calculated risks. Everything must be structured and approved by the New York Times, Harvard, and the Federal Government before it's safe to do. This same person often says that startup founders who make fortunes were "lucky", and will say the same thing about early Bitcoin adopters in a few years if it succeeds.<p>But what he never realizes is that you can't be lucky if you don't take risks.
