I know, read my first post in this thread.
But countries M0s are not the same as their M1. It would be more reasonable to compare with their M0, since the day Bitcoin start to have fiduciary money, it will have aggregates that are larger than this so-called "market cap". And btw, if you compare with M0, we've already passed much more countries, since M0 <= M1.
I did not find a ranking of countries per M0 TDV though....
