>I believe there are only 4 addresses with more than 100,00BTC each. Satoshi is 1. I believe Bitfinex is 3.

The flaw in your analysis is that you assume that there's a one to one relationship between an address and a person. This is not the case because a typical bitcoin wallet has hundreds of addresses and address reuse is discouraged. Therefore your conclusion that bulgaria is the nth largest bitcoin holder in the world because there are are only n addresses with balances larger than it is incorrect.

Sorry, I was also quoting a number of other sources. They may have done the analysis the same way of course. [1] You certainly do raise a good point however, I'm open to retracting that since to your point it's probably not possible to know for a fact. My bad!
