There are roughly a million addresses holding multiple Bitcoins, according to on-chain analytics. Additionally, starting from about mid-2016, the number of "wholecoiner" addresses with over 1BTC has doubled. During the previous cycle peak, it peaked at slightly over 800,000 addresses, but when investors accumulated during the cycle bottom in late 2022 and early 2023, it climbed. Given that there are over 56 million millionaires worldwide, this figure is astonishing.
