Sources and Caveats
Data is compiled in this spreadsheet.
Bitcoin, Litecoin and Dogecoin come from https://bitinfocharts.com/. Numbers are approximate as their data is not broken down by percentile.
Ethereum data comes from BigQuery and is processed by this notebook. Only includes non-contract addresses.
Crypto data includes the “institutional” addresses such as exchanges. For example, the top Ethereum address is one of Binance’s, meaning that it isn’t all owned by one entity (although some might argue about that.)
American data comes from The Federal Reserve’s website.
World data comes from The World Inequality Database.
