Nice analysis and article! The possibility chapter leaves me with a big question. How did you end up at the market capitalization of over ~$1.75 Trillion USD based on the things listed in the possibility chapter? I don't seem to be getting anywhere other then that it is roughly 1/4th of the total value of the transactions Ripple accounts for. Since this is a very important factor for the value of each coin I'm curious how you derived Ripple's market cap.
