The cryptocurrency system is a peer-to-peer open-source software, meaning computers are part of a mining process for coins. Our idea is to calculate such market price for pretty arbitrary a set of volumes: 10, , , btc. For example, a genuine market order for BTC on MtGox will be executed immediately and it will shift the price a lot, so the resulting average price the execution price will be much worse than the current price. We think that Bitcoin has value. Our idea is simple: to calculate the median price between best bid and best ask for any new time slot. Our chart reflects these phenomena. But until then we can empirically separate trades using currently available order books best bid and best ask prices as a reference.
