The Bitcoin Blasphemy
Whenever I read a story about Bitcoin, the virtual currency that has been so much in the news these days, I think about a man named Dee Hock. In the early 1970s, Hock created the credit card system that we now know as Visa. Hock was a man who liked to think grandiose thoughts. When it came to Visa, and credit cards in general, Hock used to describe them not just as a way to get a short-term loan but as a new kind of payment system, an exchange of value that was on par with, and that competed with, cash.
