Large BTC transactions
Bitcoin transfers of 10 BTC or more, pulled from confirmed blocks and classified by whether they touch a known exchange wallet. Coins moving onto an exchange often precede a sale; coins moving off often signal accumulation.
What a Bitcoin whale is
A whale is an address or entity holding enough bitcoin that its trading can move the market. There is no official threshold; in practice the term covers holders from a few hundred coins upward. The reason whale activity gets watched is simple mechanics — in a market with finite order-book depth, a single large seller can move price more than thousands of small ones.
This page uses a 10 BTC floor for individual transfers, which is well below whale territory for a single holder but is the level at which transfers stop being ordinary retail activity and start being worth classifying. The filter is adjustable once signed in.
Why exchange flow is the part that matters
Most large Bitcoin transfers are uninteresting. Exchanges shuffle coins between hot and cold wallets constantly, custodians rebalance, and holders move funds between their own addresses. None of that says anything about intent. What carries information is the direction relative to an exchange.
Coins moving onto an exchange are a precondition for selling — you cannot sell on a venue you have not deposited to. Coins moving off an exchange into self-custody are the opposite: capital being taken out of immediate selling reach, usually to hold. Neither is a guarantee, but the aggregate direction over days is a genuine read on holder behaviour, which is why this tracker classifies every matched transfer as inflow, outflow, or wallet-to-wallet rather than just listing big numbers.
What this tracker can and cannot see
Classification depends on a list of known exchange addresses, and no such list is complete. Exchanges create new addresses routinely, and some deliberately avoid clustering. That means coverage is partial: a transfer shown as wallet-to-wallet may in fact touch an exchange whose address is not recognised. The tracker also cannot see anything that never reaches the blockchain — trades that happen inside an exchange's own ledger, or over-the-counter deals settled off-chain, are invisible here regardless of size. Both limitations bias the picture toward understating real flow, which is why the page is labelled Beta and why flow direction is best read as a trend over days rather than a verdict on any single transaction.
Common questions
Do I need an account to see the feed?
Yes, and it is free — no card required. How the tracker works and what it misses is explained in full on this page for everyone; the live transaction feed and 15-day flow history require signing in.
Does a large exchange inflow mean the price will fall?
Not reliably. Deposits are a precondition for selling, not proof of it — coins are also deposited for collateral, transfers between venues, or custody changes. Read sustained directional imbalance over days, not single transactions.
Where does the transaction data come from?
Confirmed blocks read directly from public Bitcoin blockchain data, matched against a list of known exchange addresses. Fifteen days of classified flow history is persisted so the trend is visible, not just the latest block.
Why is it labelled Beta?
Because exchange address coverage is partial and the all-transfers view is a best-effort sample rather than an exhaustive index. The classification is real, but the totals should not be treated as complete.
