Bitcoin Q&A: Price Volatility, Pegging, Stability

Exchange rates in Bitcoin. Bitcoin is traded on international markets against 30-45 national currencies, in real-time. It's affected by fluctuations between those currencies indirectly. The exchange rates are defined by market dynamics (supply and demand). It is still a very small currency; it was a global currency from the day one but it is still small in size, therefore it has more volatility than many of the currencies you're used to. Over the last seven years we've seen that the volatility has gradually reduced; as it gets bigger, it becomes more stable.
