Cryptocurrencies have a lot of potential, both as major innovations in private money and for their usefulness in protecting financial privacy against state oppression. However, I also think that Bitcoin will not survive. The leading innovators seldom survive because with open competition competitors learn from the innovators' design mistakes and produce superior products that eventually drive the earlier models out. Bitcoin also has major design flaws, most notably, an innate tendency towards centralisation in the bitcoin mining industry, that undermine its long-term viability.
I cover Bitcoin in Chapter 4 of New Private Monies and in "Contemporary Private Monetary Systems," pp. 213-253 in L. H. White, V. J. Vanberg and E. A. Köhler (eds), Renewing the Search for a Monetary Constitution, Cato Institute, Washington DC, 2015.
