What would be needed: An intermediate currency between public currencies and Bitcoin
Public currencies (dollar, euro, etc.) are currently characterised by extremely rapid money supply growth; this will inevitably lead to a fall in the value of these currencies (in their ability to purchase goods or assets) and to declining confidence in them. Bitcoin, in contrast, is characterised by the exogeneity and, increasingly, the stability of its supply; this gives rise to drastic volatility in its price since all changes in demand for it pass through prices, which will eventually discourage demand and prevent Bitcoin from becoming a reserve currency. What would be needed, therefore, is an intermediate currency between public currencies and Bitcoin: a currency whose supply would not increase excessively but would not be rigid either. There should be a currency whose supply partly compensates for changes in demand, so as to avoid excessive movements in the price of that currency or in its interest rates .
