Bitcoin’s Early Days: Built by Retail Pioneers
Bitcoin wasn’t always an asset class for Wall Street or governments - it was built and distributed by everyday individuals. Back in March 2013, the combined value of all bitcoins in circulation first crossed $1 billion, at a price around $90 per BTC. At that time, there were no hedge funds, no ETFs, and no corporate treasuries buying in - just a handful of tech-savvy enthusiasts trading on early exchanges like Mt. Gox. Major institutional investors were largely skeptical, citing exchange hacks and an unregulated market - sentiment captured in early-era reporting like The Verge’s archive. This grassroots phase laid the foundation: retail investors (and miners) collectively accumulated Bitcoin long before any institution dared put it on a balance sheet.
One legendary individual is Bitcoin’s mysterious creator Satoshi Nakamoto, who is widely estimated to have mined ~1 million BTC in the early days. Satoshi’s untouched stash about 4.6% of supply has never moved, making Satoshi arguably the single largest known holder. Many other early adopters also mined or bought cheap BTC and simply held on. Some of those ancient wallets are only now, in 2025, beginning to stir. In July 2025, for example, a 2011-era whale moved 80,000 BTC after 14 years of dormancy an unprecedented transfer analysts believe came from an early miner. These cases underscore how the first generation of holders were predominantly individuals - some who became billionaires simply by hodling.
Who Owns Bitcoin Today? Individuals vs. Institutions
Contrary to the popular narrative, individuals still hold the majority of Bitcoin. Fresh research published in August 2025 by River (a Bitcoin-focused financial firm) estimates that individuals control ~65.9% of circulating BTC (~13.83 million coins) dwarfing the shares held by funds, companies, or governments. Despite over 15 years of growth and rising institutional interest, nearly two-thirds of Bitcoin’s supply remains in non-institutional hands. As Nasdaq’s market analysis put it earlier this year, “more than 85% of Bitcoin remains outside institutional hands.” (Nasdaq)
On the institutional side, the pie is growing but still relatively modest in aggregate. River’s breakdown attributes ~7.8% of supply to ETFs and funds (about 1.63 million BTC) and ~6.2% to corporate treasuries (about 1.30 million BTC) (River Business Report 2025; CoinDesk summary). That combined ~14% is significant - but still a minority relative to the global swarm of individual holders. For context, public ETFs alone were already approaching 1 million BTC by late 2024 and have continued accumulating through 2025.
Governments remain a tiny but noteworthy slice at ~1.5% of supply (about 306,000 BTC), including seized or strategically held coins. Meanwhile, lost coins - wallets that haven’t moved in many years - are estimated around 7.6% (~1.58 million BTC), effectively reducing the active supply (River Business Report 2025).
Key takeaway: As of 2025, retail individuals remain the largest collective owners of Bitcoin. ETFs, corporations, hedge funds, and governments are growing in influence, but Bitcoin is still “of the people.” (Nasdaq)
The Tide Is Turning: Institutions Are Buying, Retail Is Selling
If individuals built Bitcoin’s early treasury, institutions are now catching up fast. River’s 2025 data shows the institutional buckets (funds + companies) growing sharply year-over-year as spot ETF inflows compound and more corporates adopt treasury strategies. Several trends illustrate this “handover”:
- Old wallets are moving: Dormant addresses from 2010–2012 have sprung to life, suggesting some early miners are cashing out or redistributing coins - see the 80k-BTC move above.
- ETF accumulation is relentless: U.S. spot Bitcoin ETFs have become a dominant conduit for institutional exposure, with holdings concentrated in products like BlackRock’s iShares Bitcoin Trust (IBIT) and Fidelity’s FBTC (CoinShares 13F study). BlackRock’s IBIT even became the world’s largest Bitcoin fund within months of launch (Reuters).
- Sovereign wealth is nibbling: In a notable UAE angle, Abu Dhabi’s Mubadala disclosed ~$408–$437 million in IBIT via SEC filings, marking one of the largest sovereign allocations to a spot Bitcoin ETF (Nasdaq; Reuters filings wrap; Reuters follow-up).
What This Means for Bitcoin’s Future
Decentralization vs. concentration. A wide base of individual holders has made Bitcoin resilient and decentralized. Even with rising ETF and corporate ownership, the majority of BTC remains broadly distributed (Nasdaq). Over time, if ETF and corporate treasuries keep compounding, more coins will sit in large institutional wallets - though ETFs ultimately represent thousands of underlying shareholders.
Market dynamics. As institutions own more Bitcoin, some expect lower long-run volatility but higher correlation with traditional risk assets. Portfolio-driven flows from ETFs and funds can provide a buyer of last resort on dips, yet also tie Bitcoin more closely to macro cycles—an evolution visible in 2024–2025 trading (Nasdaq).
Supply squeeze potential. Bitcoin’s fixed supply is the ultimate trump card. With ~19 million mined and large, sticky pools (ETFs, treasuries, OG wallets, lost coins) removing float from the market, net available supply keeps shrinking. River’s 2025 figures imply ETFs and funds (~1.63M BTC) plus corporate treasuries (~1.30M BTC) now hold nearly 3 million BTC collectively - versus ~900k BTC still to be mined over the next century (River Business Report 2025). If sovereigns and pensions scale allocations from tiny baselines, even fractional bids could create durable supply shocks.
The answer to “Who is the biggest Bitcoin holder?” isn’t BlackRock or Michael Saylor - it’s the collective retail community of millions worldwide. They still own the lion’s share (~66%) of all Bitcoin. But the handover is underway: institutions are steadily carving out a larger piece, with ETFs, corporate treasuries, and even sovereign wealth funds now persistent buyers. Bitcoin’s appeal - provable scarcity and decentralization - is unchanged even as coins change hands. The builders were retail; the next chapter will feature both Main Street and Wall Street - and perhaps, increasingly, Abu Dhabi’s Corniche and other sovereign avenues too.
