“It should be no surprise to any student of economics that when government has a monopoly on money, it will be mismanaged. A better approach would be a free market in money: currency competition among entrepreneurs. Bitcoin is one of the opening salvos in this battle. In some respects it is very promising as an alternative currency and as a possible wholesale replacement for a national currency. In other respects it falls short. Bitcoin is a fiat currency that has achieved popularity and value without the mandate of a government legal tender law. On the contrary, the government strongly discourages bitcoin use and has used regulations to frustrate its adoption.”
