What determines the price of Bitcoin?
The price of the Bitcoin price is measured against fiat currencies, stories such as US dollars (BTCUSD), Chinese yuan (BTCCNY) or euro (BTCEUR). Bitcoin is therefore superficially similar to any symbol exchanged in foreign trade markets.

However, unlike fiat currencies, there is no official price for Bitcoin; only several specific averages in price data of global exchangers. Bitcoin Average and CoinDesk are two index stories that inform the average price. It is normal for Bitcoin to be exchanged in an exchanger at a price slightly different from the average.
