Have you incorporated the Ron-Shamir Entities into this? The paper's a little dated and it's unclear whether the balances on pg. 11 are still accurate, but it'd mean at least two additional billionaires (Entities A and C) who have taken pains to make their large holdings non-obvious.
That study has very questionable assumptions about associations of addresses. For example, it was rather clear that some of the "wealthy holders" that they listed were actually hot wallet accounts held by major exchanges. Other thing I found sketchy was their assumption that if one address sent money to another, that the two were likely owned by the same person, which is true for change accounts when making transactions, but there is no way to tell whether the change address is the first or the second in the transaction.
Rpietila, so you are saying that new made bitcoin millionaires have the power to do wonderful things for the world if I understand you correctly. What makes you think that these millionaires will be different than old school millionaires?
