Bitcoin itself is useless as a currency, a currency needs to have stable purchasing power, i.e. One coin will purchase roughly the same amount of goods next year as it does this year. Bitcoin by design doesn't allow this. Hopefully one day we will create a currency where the supply is determined more by demand, so it has a stable purchasing power. This'll make it much more practical for businesses and consumers to use for buying goods and services.
