BTC balances by exchange
Bitcoin in the wallets exchanges publish, at 00:00 UTC Oct 6, and the netflow of the day before. Robinhood’s wallets have not moved since Jun 13, so no netflow is shown.
ETH balances by exchange
Ether in the wallets exchanges publish, at 00:00 UTC Oct 6. Robinhood’s ether wallets have not moved since Apr 21.
How to read this data
What the numbers measure and why they matter.
Netflow
netflow = inflows − outflowsCoins deposited to exchanges minus coins withdrawn. Negative netflow means more coins are leaving.
Why it matters
Coins sent to exchanges are often there to be sold; coins withdrawn are usually going into long-term storage.
Balances
The coins held in known exchange wallets. A steady decline means less supply is readily available to sell.
About this page
Exchange flows track coins moving onto and off crypto exchanges. Netflow is deposits minus withdrawals: a positive figure means coins arrived, a negative one means more left than came in. This page builds bitcoin and ether netflow and balance series from the wallets that exchanges publish for their proof of reserves, then lists the balance held at each exchange.
Traders watch bitcoin exchange reserves because coins sent to an exchange are often there to be sold, while withdrawals usually go into long-term storage. A steady fall in balances means less supply sits ready for sale. One day's flow can also be an exchange moving coins between its own wallets, so the 7-day and 30-day figures say more than any single day.
Balances come from DefiLlama's CEX transparency data, read about every 12 hours and recorded daily. Exchanges that keep their addresses private, Coinbase among them, are not counted, and neither are most US spot ETF coins, which sit with custodians. When the tracker adds or drops a wallet, the jump in the balance is not counted as a flow.
Questions
Short answers to what people ask most.
Wallets that exchanges publish for proof of reserves hold 1.31 million BTC, a change of +0.3% over 30 days. Exchanges with private wallets are not counted.
Deposits minus withdrawals for a coin. A negative reading means more coins left the tracked wallets than arrived.
More bitcoin was withdrawn from the tracked exchanges than deposited. It is often read as holders moving coins into storage, which leaves less supply on exchanges ready to sell.
Ten exchanges that publish wallet addresses for proof of reserves, among them Binance, Bitfinex, OKX, Robinhood, Bybit, Gemini and Deribit.
No. Custodians hold most ETF coins, and Coinbase publishes no wallet addresses, so those holdings never appear in the balances.
