How significant are the on-chain withdrawal patterns?
Exchange outflows are measurable on-chain and reported by market trackers and analysts. Large transfers to custodial cold wallets and staking or DeFi addresses indicate long-term intent. The size of outflows, coupled with order book thinning, suggests materially reduced immediate supply for spot trading.
Bitcoin and Ethereum exchange reserves fall over 20% in 2025 as investors withdraw holdings from exchanges. Are long-term strategies driving this sharp decline?
- Bitcoin balances in exchanges declined to 2.47 million down from 3.05 million (2025) — almost a quarter.
- Ethereum reserves held near 20.6 million through May, then dropped to 17.1 million as price fell below $1,500.
- The Binance exchange, with ~600,000 BTC and ~4.5M ETH, remains the largest custodian amid widespread withdrawals.
Bitcoin and Ethereum exchange reserves are experiencing steep declines in 2025, with both assets seeing sizable withdrawals from centralized platforms. These flows reflect a shift to long-term custody and participation in decentralized protocols, reducing immediate trading supply.

Why did Bitcoin exchange reserves drop over 23% this year?
Market reporting shows exchange-held Bitcoin fell from 3.05M BTC on January 1 to approximately 2.47M BTC now. On-chain transfers to non-exchange addresses and custody wallets account for the majority of this change. Observers cite accumulation by long-term holders and increased transfers to cold storage as primary drivers.
A social update by @Darkfost_Coc highlighted the magnitude of the change and noted Binance still custodying roughly 600,000 BTC. This concentration underscores that while withdrawals are widespread, large custodians continue to hold substantial reserves.
Reduced exchange balances imply thinner order books and a smaller pool of immediately tradable coins. That can increase price sensitivity to large market orders and amplify volatility when demand shifts.
How did Ethereum reserves fall sharply after May?
Ethereum reserves were stable at about 20.6M ETH through May. Following a price drop below $1,500, exchanges saw accelerated withdrawals, reducing reserves to approximately 17.1M ETH between May and September — a >20% decline in four months.

var adsindex = isNaN(sessperindex) ? Math.floor(Math.random() * adscodesHtx.length) : sessperindex;

sessperindex = adsindex === adscodesHtx.length – 1 ? 0 : adsindex + 1;
sessionStorage.setItem(“adsindexHtx”, sessperindex);
}
})();
Data shows that sizeable fractions of withdrawn ETH moved to staking services and DeFi smart contracts, reducing circulating supply on exchanges and shifting liquidity toward protocol-level use cases.
What role do major custodians play?
Major exchanges such as Binance continue to hold large custody positions — reported at ~600,000 BTC and ~4.5M ETH. This concentration means that although overall reserves declined, centralized platforms still manage sizeable pools that can influence short-term liquidity.
