The single largest Bitcoin wallet is believed to belong to Satoshi Nakamoto, the pseudonymous creator of Bitcoin. Estimates put this stash between 750,000 and 1.1 million BTC, spread across many early-mined addresses—never moved since around 2010. At today’s prices, that stash would be worth tens of billions to over $100 billion.
🥇 The Single Largest Bitcoin Address
The title belongs to Binance’s cold wallet (34xp4vRoCGJym3xR7yCVPFHoCNxv4Twseo), holding 248,598 BTC (worth ~$26.2 billion as of June 2025). This address alone controls 1.25% of Bitcoin’s total supply and serves as a custodial vault for user funds on the world’s largest crypto exchange 125. Key details:
-
Activity: Processes thousands of daily transactions, reflecting Binance’s liquidity demands.
-
Security: Labeled a “cold wallet,” meaning private keys are stored offline to deter hacks.
-
Market Influence: Transfers exceeding 10,000 BTC can trigger short-term price volatility.

🌍 Major Holders Beyond Single Addresses
While Binance’s cold wallet is the largest individual address, entities like Satoshi Nakamoto and ETFs control far more BTC spread across multiple wallets:
Table: Largest Aggregated Bitcoin Holdings (June 2025)
| Entity | Total BTC | % of Supply | Key Details |
|---|---|---|---|
| Satoshi Nakamoto | 968,452–1.1M BTC | ~5.2% | Coins mined in 2009–2010; untouched 14 |
| U.S. Spot Bitcoin ETFs | 1.25M BTC | ~6.3% | BlackRock (575,810 BTC), Fidelity (350,000 BTC) 34 |
| Coinbase (Exchange) | 993,230 BTC | 5.0% | Combined user/corporate funds 3 |
| Strategy (MicroStrategy) | 592,100 BTC | 2.98% | Publicly traded company; led by Michael Saylor 14 |
| Governments | ~471,000 BTC | 2.37% | U.S. (198,012 BTC), China (190,000 BTC) 34 |
Key insights:
-
Satoshi’s stash: Spread across ~20,000 addresses, these coins are considered permanently inactive. Any movement would crash markets 14.
-
ETF dominance: BlackRock’s iShares Bitcoin Trust (IBIT) became the world’s third-largest holder in just 18 months, signaling Wall Street’s takeover 38.
-
Lost Bitcoin: ~1.6M BTC are irrecoverable (e.g., Mt. Gox’s 79,957 BTC in address

⚖️ Why the Largest Wallets Matter
Bitcoin’s wealth concentration poses systemic risks and opportunities:
-
Market volatility: A single whale selling 10,000+ BTC (~$1B) can trigger 5–10% price swings. Exchanges mitigate this via OTC desks 48.
-
Decentralization myth: The top 1,000 addresses control 15% of all BTC—a sign of growing centralization 5.
-
Security targets: Large wallets attract hackers, prompting advanced protections (multi-sig, air-gapped hardware) 67.
-
Network health: Whales provide liquidity but could destabilize Bitcoin if colluding (e.g., 51% attacks).

-

Conclusion
Binance’s cold wallet remains the world’s single largest Bitcoin address, a testament to exchanges’ custodial power. However, institutional entities—ETFs, governments, and corporations—now control more BTC than any individual whale. This shift toward regulated holders reduces panic-selling risks but challenges Bitcoin’s decentralized ethos. As ownership consolidates, the network’s resilience will depend on transparent custody and broader distribution.
