In 2010 Dave Jamieson wrote Mint Condition, the seminal book on the baseball cards bubble of the late 1980’s and early 1990’s. In this recent interview on Bloomberg Odd Lots he describes the background, the build-up and the eventual fall of this bubble. Baseball cards went from being a niche hobby to a big business in the space of a few years. Many new entrants began producing cards, flooding the market with variations on what is essentially a picture on a piece of cardboard. For some the cards became an alternative form of currency, with kids and adults alike buying them with a view that the prices would increase and they would make a fortune. It was a classic Ponzi bubble.
The development of cryptocurrencies today mirrors that of baseball cards. In the space of a few years we’ve gone from a handful of alternative currencies to dozens of initial coin offerings (ICO) a week. Each ICO claims to offer a unique angle on why it should flourish, but few pass the sniff test.
