With just 0.3 bitcoin you could be a millionaire in future: we do the maths

Update (November 1, 2026): we have redone the calculation with new figures. According to UBS’s Global Wealth Report 2026, which continues Credit Suisse’s earlier survey, there were around 57.5 million US dollar millionaires worldwide at the end of 2025; Capgemini, using a narrower definition of investable assets only, counts around 25.3 million for 2025. Dividing the maximum of 21 million bitcoin by the UBS figure leaves around 0.37 BTC per millionaire, or around 0.35 BTC using the 20.1 million mined to date.
