Who Really Owns Bitcoin? The Balance Is Slowly Shifting. Individuals still hold 66.3% of Bitcoin's total supply, while businesses, funds, ETFs, and governments collectively account for around 17%. But here's where things get interesting. Only 4.4% of BTC remains to be mined, and another 12.3% is attributed to lost coins and Satoshi, much of which may never circulate. As institutional adoption grows, accumulating significant amounts of BTC increasingly means buying from existing holders rather than relying on new supply. Bitcoin is still largely in individual hands, but the ownership landscape is changing. The real question is how much supply long-term holders will be willing to sell.
