If Bitcoin stays small enough, it is considered a nuisance or a curiosity. If a non-governmental currency grows to the size of a governmental currency, then the simple model gets complicated by regulators, arbitrage, and a very confused power structure. Bitcoin is not one entity with one voice. The unilateral actions will have to come from the countries, how they accept cryptocurrencies, how they handle the taxes, and whether they offer a competitive currency. Interesting money times ahead, and personal finance plans may be reshuffled.
