According to the latest on-chain data as of June 20, 2025, the ten most heavily loaded Bitcoin addresses collectively hold approximately 1.10 million BTC, representing 5.55% of the current circulating supply (19.88 million BTC). In 2023, the top ten held 1.12 million BTC, accounting for 5.66%, indicating a slight decline in concentration. However, the composition of the list has shifted notably, with several addresses showing minimal activity.
Binance Cold Wallet Maintains Top Spot, Unmoved for Over Two Years
The largest wallet remains Binance's primary cold storage address, holding 248,598 BTC. Not a single satoshi has moved from this wallet since January 7, 2023 – a period of more than two years of complete inactivity. This steadfastness underscores Binance's approach to securing its reserve assets without frequent on-chain movements.
Second place is now held by Robinhood’s cold wallet, with 140,575 BTC. Its last outgoing transaction occurred on January 8, 2025, and since then, the address has remained dormant. This represents a shift from 2023 when Bitfinex occupied the runner-up position.
Bitfinex and Binance Secondary Wallets See Reductions
The Bitfinex address has dropped to third place, containing 130,010 BTC. Over the past 30 days, it has shed about 9,000 BTC. Binance’s second cold wallet, now fourth, holds 115,032 BTC and has decreased by 19,249 BTC in the same period. These outflows may indicate routine liquidity management or customer withdrawals, but the overall volumes remain modest relative to the total holdings.
Fifth place belongs to the Bitfinex hack recovery wallet, with 94,643 BTC – assets recovered after the 2016 breach. This wallet has also seen minimal movement, suggesting a long-term holding intention.
Anonymous Wallet and Government Seizures in Top Ten
Sixth is the notorious Mt. Gox hacker wallet (starting with “1Feex”), holding 79,957 BTC. Stablecoin issuer Tether ranks seventh with 78,647 BTC. The eighth-largest wallet, with 78,317 BTC, belongs to an unidentified entity – the only anonymous holder among the top ten. The U.S. Federal Bureau of Investigation (FBI) holds ninth place with 69,370 BTC, seized from the Silk Road hacker.
Rounding out the top ten is a Binance-managed address holding 68,200 BTC, serving as a reserve for its wrapped bitcoin (BTCB) project. Nearly all wallets in the top ten exhibit extremely low outbound activity and static balances, suggesting intentional long-term positioning rather than speculative trading.
While the distribution among the largest Bitcoin holders has seen modest reshuffling, the concentration remains significant. These silent wallets act as barometers of institutional custody practices and long-term capital allocation within the Bitcoin ecosystem.
