Key points to remember:
-
Since 2024, spot ETF inflows and outflows have been the primary driver of Bitcoin’s green and red days.
-
With foreign exchange balances near multi-year lows, any large orders spread further through the book.
-
Large holders often split trades or use over-the-counter desks, thereby mitigating visible “portfolio-displaced” shocks.
-
Funding rates, open interest, the dollar, and yields often determine the direction of the day more than any portfolio.
Everyone “knows” that whales move Bitcoin (BTC), and they can always push prices higher.
Since the advent of spot exchange-traded funds (ETFs), the direction of Bitcoin often depends on ETF inflows and outflows. It also depends on the amount of tradable supply actually present on exchanges, not the whim of a single wallet. BlackRock’s iShares Bitcoin Trust ETF (IBIT), for example, now holds over 800,000 BTC on behalf of thousands of investors. The flows through this pipe can rival any holder.
Add to that the positioning of derivatives and the broader mood of risk aversion and risk aversion, and you get the real picture.
This guide walks through the history of whales, explains the market mechanics that actually matter, and gives you a quick data checklist for playing the tape without searching for every “whale just moved” virus alert.
What counts as a “whale”?
In crypto, a whale refers to an onchain entity holding at least 1,000 BTC. Many dashboards specifically track the 1,000 BTC-5,000 BTC range.
An entity is a group of addresses controlled by the same owner, not a single wallet. Analytics companies aggregate addresses using heuristics such as co-spending and change detection to ensure that a holder is not counted multiple times on separate filings.
This distinction is important because the raw number of “rich list” addresses can overstate concentration. Large services such as exchanges, ETF custodians and payment processors operate thousands of wallets, and labeled clusters help separate these from end investors. Academic and industry research has long cautioned against drawing conclusions from address data alone.
The methodologies differ. Some whale metrics include service entities such as exchanges, ETFs or custodial pools, and corporations. Others exclude known exchange and miner clusters to focus on true investor whales.
In this guide, we use an entity-based convention of ≥1,000 BTC and clearly note where service wallets are included or excluded so you know exactly what each metric represents.
Did you know? The number of entities holding at least 1,000 BTC recently exceeded 1,670, the highest level since early 2021.
How concentrated is BTC today and who owns it?
Since the launch of spot ETFs in the United States, much of Bitcoin’s visible supply has shifted to custodial pools. BlackRock’s IBIT alone holds around 800,000 BTC, making it the largest known holder. However, it is held on behalf of many investors and not as a single balance.
Among issuers, U.S. spot ETFs collectively hold about 1.66 million BTC, or about 6.4% of the total supply of 21 million. This centralizes execution even though underlying ownership remains widely distributed.
Corporations are another important group. MicroStrategy recently disclosed around 640,000 BTC. Miners, exchanges, and unlabeled long-term holders make up the rest of the largest clusters.
Meanwhile, tradable float on centralized exchanges continues to decline. Balances tracked by Glassnode fell to a six-year low of around 2.83 million BTC in early October 2025. With fewer coins on exchanges, large orders tend to drive prices further.
Keep in mind that lists rich in “top addresses” often overestimate concentration because large services operate thousands of wallets. Entity-level grouping and labeled wallets, such as those owned by ETFs, exchanges, and companies, provide a clearer picture of who actually controls the coins.
Did you know? US spot ETFs now hold over 1.6 million BTC, representing just over 6% of the total supply held by institutions and funds.
Can whales overturn the market during the day?
Large, aggressive orders can cause prices to fluctuate sharply, particularly as order book depth decreases. During volatile times, liquidity often disappears and large sell blocks can have an outsized impact. This is the basic microstructure of the market.
For this reason, many large holders avoid “checking the book.” They split their orders or use over-the-counter (OTC) desks to execute blocks silently, reducing their footprint and information leaks. In practice, a significant portion of whale activity occurs off-exchange, reducing the visible impact of any single wallet in public places.
Over the course of the cycles, the whales do not always “pump”. Studies combining stock market and onchain data show that large holders often sell hard, especially when smaller traders buy. Their flows can temper rallies rather than direct them.
A look at 2025 fits this pattern: As prices rose above $120,000, alongside strong ETF inflows and broad accumulation, “mega-whales” took profits at the margin. Intraday management often followed ETF flows and available liquidity more than any whale portfolio.
Did you know? A well-known “OG” whale recently sold thousands of BTC to buy nearly $4 billion worth of Ether (ETH).
What actually makes markets turn green or red most of the time?
Since January 2024, ETF spot flows have become one of the most reliable daily Bitcoin signals. Strong weekly inflows have often coincided with pushes to new highs, while weaker or negative numbers tend to align with down days. Pair this with a live feed dashboard to track how US ETFs are doing every session.
Liquidity on stock exchanges is equally important. With balances on centralized exchanges falling to around 2.83 million BTC, a six-year low, the supply is now less easily tradable. Lower liquidity means that even routine buy or sell programs further encroach on the order book, amplifying price fluctuations among all types of participants.
Positioning and leverage often lead to intraday fluctuations. When funding becomes rich or deeply negative and open interest (OI) rebuilds after a wipeout, the path of least resistance can change quickly.
Continue to monitor funding and OI to gauge attendance. Recently, with around 97% of supply in profit and a slight easing of long-term holder distribution, markets have become more sensitive to new flows and news.
Finally, the macro always determines the beta version of the crypto. Dollar trends, US yields and broader risk appetite often move in sync with Bitcoin’s daily direction. On quieter data days, ranges tend to compress; when macro heats up, crypto usually follows.
Quick Checklist
-
ETF feed: Track yesterday’s net inflows/outflows and total turnover.
-
Liquidity: Monitor trade balance trends and order book depth across major platforms.
-
Positioning: Review funding rate heatmaps and OI rebuilds after liquidations.
-
Macro band: Monitor the dollar index, the 10-year yield and the strength of the stock market.
Are Whales Still Setting Bitcoin’s Tone for the Day?
Whales can move prices, but they rarely decide the end of the day. When liquidity decreases, a single large order can push the move further than usual. Most large holders now split trades into smaller clips or route them through over-the-counter desks, mitigating the impact seen on public books.
Since 2024, ETF spot flows have been the main force driving daily direction, alongside the large trading volumes flowing through these funds. Observing net flows and turnover from the previous day gives a clearer idea of this bias.
With tradable supply on exchanges near multi-year lows, even a marginal buyer or seller – whether a whale, a market maker or a retail wave – can cause prices to move more than normal. Larger holders often sell to strengthen their holdings rather than “inflate” them, a tendency that tends to cap rallies rather than fuel them.
Macroeconomic factors still drive much of the action. Changes in the dollar and US yields influence risk appetite, pulling Bitcoin in the same direction.
