The biggest known BTC and ETH addresses on-chain — refreshed daily. Track who's holding, who's been dormant for years, and watch for the rare moments when a long-sleeping wallet finally moves. Our tracking registry currently covers 27 Bitcoin addresses and 14 Ethereum addresses, jointly accounting for roughly $754.31B in on-chain value at reference prices.

USD values calculated at a reference price of $95.0K per BTC; live prices replace these once the page loads. Balances refreshed daily from public blockchain APIs. Cluster rows (badged RESEARCH ESTIMATE, DISCLOSED HOLDINGS, or SEIZED HOLDINGS) are aggregate figures across multiple custody addresses, not single-address balances.

Cryptocurrency markets are unusually transparent: every balance and every transfer is visible on a public ledger, even when the identities behind addresses are not. That property turns address-level holdings into one of the few genuine information advantages a retail investor has access to. Traditional equities offer 13F filings months after the fact; on-chain markets show the same kind of large-holder data in near real time, for free.
Concentration is the first thing the data reveals. Bitcoin is often described as decentralized, but the distribution of balances is heavily skewed. Roughly 0.03% of Bitcoin addresses — those holding more than 100 BTC — control over 60% of the circulating supply. The numbers are even more concentrated for Ethereum once you account for the Beacon Deposit contract, which alone holds the majority of all ETH currently staked. Understanding that the top of the rich list is dominated by custodians, not individuals, is the first step in reading whale data correctly.
The second signal is movement. Most exchange cold wallets rebalance on predictable cadences and produce on-chain noise that experienced observers learn to filter out. The interesting events are the outliers: an address that has been silent since 2011 producing its first outbound transaction, a treasury address consolidating into a new multi-sig, or a known institution moving size into a single exchange counterparty. These movements often precede measurable price action by minutes or hours, which is why whale-watching has become a core analytical discipline for active traders and a useful sanity check for long-term holders.
Finally, dormant supply tells its own story. Chainalysis estimates that roughly 1.5 million BTC is permanently lost to forgotten keys, broken paper wallets, and dead hard drives. Another large block sits in addresses that have been inactive long enough to be effectively out of circulation but are not necessarily lost — early miners, long-term holders, and a handful of identifiable individuals who acquired coins in the first three years of Bitcoin's history. Tracking which of these wallets remain quiet, and which finally move, is one of the more durable analytical frameworks in the space.
The three sub-pages serve different questions. The Rich List answers "who holds the most right now" — useful for understanding market structure and exchange dominance. Sleeping Giants answers "what supply is effectively out of circulation" — useful for sentiment context and supply-side analysis. Awakenings answers "what just changed" — useful for short-term news flow and trade timing. Start with the Rich List to orient yourself, then use the other two for ongoing monitoring.
We maintain a curated registry of large, publicly-known BTC and ETH addresses and refresh their balances and last-activity timestamps once per day from public blockchain APIs — Blockstream Esplora for Bitcoin, public RPC and optional Etherscan for Ethereum. Addresses are labeled where attribution is publicly documented through entity disclosures, court filings, or established research firms. Anonymous addresses with no attribution are labeled as such; we do not speculate about ownership.
A whale wallet is a single on-chain address — or sometimes a clustered set of related addresses — that holds an unusually large balance relative to the rest of the network. In Bitcoin, the conventional threshold is 1,000 BTC or more; in Ethereum, holdings above 10,000 ETH are commonly considered whale-tier. The term is informal: there is no protocol-level definition of a whale. What matters is the disproportionate market influence a holder of that size can exert if they choose to transact.
Blockchain analytics platforms identify large addresses by scanning the chain for high balances, then attempting to cluster them by transaction patterns. Attribution — linking an address to a real-world entity like Binance or Coinbase — is harder. Confirmed labels usually come from one of three sources: the entity disclosing the address themselves, court filings or regulatory documents that name a wallet, or research firms like Arkham and Chainalysis publishing investigations. Our registry uses only addresses with at least one of those sources backing the label.
Exchanges custody the assets of millions of customers in a small number of pooled cold-storage addresses. The result is that a handful of exchange wallets effectively represent the holdings of many thousands of individuals. Binance, Bitfinex, Coinbase, Kraken, and Robinhood collectively hold a meaningful share of all Bitcoin in circulation across just a few addresses each. This skews the rich list toward custodial entities rather than individual whales — and is one reason on-chain rich-list rankings are not the same thing as a list of the wealthiest individual crypto holders.
Our scheduled refresh function runs once every 24 hours at approximately 12:00 UTC. It pulls the current balance and last-outbound-transaction timestamp for every address in our tracking registry from public APIs — Blockstream Esplora for Bitcoin, and a public Ethereum RPC with optional Etherscan supplementation. The refreshed snapshot is cached and served via our API endpoint until the next run. Between refreshes the page falls back to a recent committed snapshot, so a temporary API outage never leaves the page empty.
Our registry is intentionally curated rather than algorithmic — we focus on addresses with editorial significance (top balances, known dormant wallets, public attribution). If you have a specific address you would like added, the contact page is the place to flag it. Adding an address takes a few minutes and the next daily refresh will populate its balance and dormancy data automatically.
An awakening is the moment a long-dormant address produces its first outbound transaction in a year or more. These events draw attention because they can signal supply that was previously assumed lost or held with diamond hands is now in motion. Awakenings are not automatically bullish or bearish: a Satoshi-era miner moving coins to a known exchange suggests selling pressure, while the same coins moving to a different self-custody address may simply be a security upgrade. Our awakenings feed flags the events and the editorial team adds context where the on-chain signal is significant.
