With Monero, the blockchain provides no help in determining balances. So the distribution of holdings must be constructed purely theoretically. What we use in the analysis of this post is just the following information:
- Number of XMR (about 2.2 million when this was done);
- Assumption that the distribution follows power law for the highest 3% of the holders (it does if we are talking about general wealth) - the power law distribution has the property that the owners of 100-200 coins collectively own the same number of coins as the ones owning 200-400 coins etc. But their number is 2x higher (because the other group was 2x richer), and the density is 4x more (because not only there was 2x the number of people, but also the bracket is in absolute terms only half the size);
- Below that, the distribution forms a nice bulge centered around the median holding and drops quickly towards insignificant holdings;
I have calculated 2 possibilities that give the result for both 5,200 and 13,200 holders. The results are presented in logarithmic brackets that are 0.333 log10 units wide (unlike my usual precision of 1 log unit, this gives 3 times more information). The exact form of the very top (holdings of the top-5 or so holders) affects the distribution somewhat, but with XMR it cannot be deduced either directly or statistically. I have assumed that the Case A scenario has a large outlier but Case B does not have it.
