The Bitcoin Price Calculation
Maybe you've been looking at the Bitcoin price for a while now. Or maybe you checked at your favourite exchange how much Bitcoin that €20 credit would be on the postcard?
You might find that the actual amount is a little different. Maybe you feel a little cheated, or maybe you feel very lucky to have recieved more than expected
The reason is that we don't use the price of just one exchange. That is far to unpredictable (volatile). Instead we take an average over a lot of exchanges. For that, we use BitcoinAverage. They have an infographic explaining the calculation.
