Bitcoin Whale Tracker

Open the Live Feed on this page. It is already filtered to Bitcoin (the BTC chain chip is selected) and lists transfers worth $500K or more in US dollars. To see only the largest moves, raise the Min cutoff to $1M, $5M or $10M. Real Bitcoin transfers load for free from mempool.space, with no API key, and the feed checks for a new block about once a minute. Each real transfer's hash links to the transaction on mempool.space, so you can check it on-chain yourself.

With no API key, the feed reads the newest Bitcoin block from mempool.space and shows each transaction in its first batch whose total output is worth $500K or more at the current BTC price from CoinGecko. Miner reward (coinbase) transactions are skipped. The sender shown is the first input address and the receiver is the largest output. Known exchange wallets (Binance, Coinbase, Kraken, Robinhood and OKX) are labelled by name. Until you add a Whale Alert API key in Settings, simulated rows are mixed in with the real ones: they show SIMULATED where the transaction hash would be, and the header badge reads DEMO.

An inflow is a Bitcoin whale transfer into a wallet labelled as an exchange, and an outflow is one out of an exchange wallet. Coins sent to an exchange are often, but not always, on their way to being sold or traded, and coins taken off an exchange often go into self-custody. Treat it as one signal, not a price prediction. Bitcoin transfers to and from known Binance, Coinbase, Kraken, Robinhood and OKX wallets are labelled with no API key needed. To see them on their own, keep the BTC chain chip selected on the Live Feed and pick the To Exchange or From Exchange type chip. The Exchange Flow tab totals inflows and outflows per exchange across every chain in the feed, not just Bitcoin.

A crypto whale is a wallet that holds or moves enough coins to stand out on-chain: exchanges, funds, early holders, miners and large traders. Because blockchains are public, their big transfers can be seen as they happen. CryptoWhaleLens watches for those transfers and labels known wallets (for example Binance, Coinbase or Kraken) so you can see who is moving money where.

Here, a transaction counts as a whale move if it is worth at least $500,000 in US dollars at the current price. Smaller transfers never enter the feed. On the Live Feed tab you can raise the cutoff to $1M, $5M or $10M to see only the largest moves.

An inflow is a whale transfer into a known exchange wallet, and an outflow is a transfer out of one. The Exchange Flow tab adds these up per exchange and shows the net flow. Coins sent to an exchange are often (not always) on their way to being sold or traded. Coins taken off an exchange are often moved into self-custody or long-term storage. Transfers between two unlabeled wallets count as plain transfers, not flows.

Not reliably. A large inflow to an exchange can come before selling, and steady outflows can mean accumulation, but whales also move funds for custody, collateral, internal reshuffles or OTC deals that never touch the order book. Treat whale activity as one signal among many. Nothing on this site is financial advice. Do your own research before you trade.

The tracker covers Bitcoin, Ethereum, TRON, Solana, BNB Chain and the XRP Ledger. Assets include BTC, ETH, USDT (on TRON and Ethereum), USDC, SOL, BNB, XRP, TRX and LINK. Real Bitcoin and Ethereum whale transfers load for free from public block data (mempool.space and Blockchair). To get live data for the other chains, add a Whale Alert API key in Settings. Without one, those chains run as a simulated demo feed, marked DEMO.

Signing up twice with the same address does not create a duplicate. To watch whale moves in real time, keep the Live Feed open. It checks for new whale transactions about once a minute.
