Bitcoin outflow: Investors pull BTC out of exchanges

Exchange bitcoin reserves fall to lowest level since 2023

According to CryptoQuant data, bitcoin reserves on the exchange have dropped to approximately 2.68 million, the lowest level since 2023. At the beginning of 2024, this number is still close to 3.2 million. Although the period experienced sharp price fluctuations, including a rebound in 2025 and subsequent correction, the downward trend continued. This means that there is a reduction in the amount of bitcoins that can be directly circulated on trading platforms. This is a signal worth watching, but it does not necessarily mean bullish.

Core Points

• Currently, approximately 2.68 million bitcoins are held on the exchange.
• At the beginning of 2024, the number is still close to 3.2 million.
• A reduction in ready-to-use supply does not guarantee an increase in prices.

The trend of 2.68 million bitcoins stranded on exchanges

This trend is not new this week. Since spring, Bitcoin reserves on exchanges have fallen to their lowest level since 2023. In less than three months, nearly 100,000 bitcoins have left platforms such as Binance, OKX and Gemini. Currently, platforms monitored by CryptoQuant hold approximately 2.68 million bitcoins. The "Exchange Reserves" indicator measures bitcoins identified as belonging to the exchange wallet. Its decline means that some coins have left these addresses and moved to other locations: such as personal wallets, custody services, institutions, over-the-counter (OTC) structures or other on-chain addresses.

2024年初，当比特币价格仍在7万美元以下时，同一指标曾达到约320万枚。此后，市场经历了多个阶段：比特币在2024年突破7.3万美元；2025年达到12.6万美元以上的峰值，随后在2026年遭遇大幅回调。在此期间，交易所储备总体呈下降趋势。

10月初，价格回升至约8.5万美元，但这并未导致大量BTC回流平台。截至10月3日，总储备量仍维持在268万枚左右。对于不打算出售的持有者而言，将比特币留在平台上并非必要之举。将其转移至个人钱包也能直接降低与交易所相关的风险。

2022年的事件早已加速了这一习惯。而2026年又引入了其他参与者：美国现货ETF、持有比特币的上市公司以及机构托管服务，这些都深刻改变了BTC的流通方式。从币安或Coinbase流出的比特币，并不一定最终进入私人个人的钱包。

This comparison is particularly obvious in Binance. Although overall reserves fell, the world's largest cryptocurrency platform saw the opposite movement in September. According to CryptoQuant data quoted by U.Today, as of September 19, its reserves reached approximately 702,900, setting a new high for the year. Therefore, a platform can enrich itself while de-transforming the overall market. This is why we cannot simply summarize the number of 2.68 million coins as "everyone is buying Bitcoin." However, the underlying trend remains clear: the number of BTC on monitored exchanges is now lower than at the beginning of 2024.

Reduction in available bitcoins does not necessarily mean a shortage

In theory, the mechanism seems simple. When investors want to sell Bitcoin quickly, they usually send their BTC to the exchange. When reserves increase significantly, theoretically more coins will enter the market. Conversely, when Bitcoin leaves the platform, this ready-to-use reserve shrinks. CryptoQuant even describes "exchange reserves" as a direct indicator of potential available supply to sellers. Historically, protracted declines have often been accompanied by a shift to off-exchange custody and can lead to lower selling pressure.

But the key word is still "potential". This summer showed this well. In August, in less than three weeks, 28,000 BTC returned to the exchange. The rebound smoothed out many of the declines accumulated in previous weeks. As a result, Bitcoin did not immediately enter a large-scale selling phase. Exchange reserves measure the asset's location rather than the owner's exact intentions.

The situation of ETFs further complicates this interpretation. In September, the U.S. spot Bitcoin ETF attracted a net inflow of $2.65 billion, the second best month since October 2025. As overall exchange reserves continue to decline, institutional demand has clearly rebounded. However, these funds operate differently than individuals opening Binance and immediately withdrawing BTC into Ledger hardware wallets. A large number of their operations are conducted through institutional custodians and over-the-counter transactions. As a result, these flows are not always as intuitive as simple exchange reserve statistics suggest.

Wallet classification and analysis limitations

Analytics companies must determine which addresses belong to Binance, Coinbase, Kraken, or other exchanges. When a platform changes its hosting architecture, creates new wallets, or transfers assets between different structures, the reading of certain data may temporarily change. This explains why absolute levels sometimes vary between different data providers. The signal is still useful, but it should not be converted into predictions. Caution is especially important today. Bitcoin has just completed a very strong third quarter, with prices rising more than 40% between July and September and stabilizing at the end of the month between $83,000 and $87,000. At the same time, CryptoQuant also noticed profit-taking and some funds returning to the exchange.

Multiple movements coexist: Bitcoin generally leaves the platform, some participants send it back, ETFs again attract capital, and other investors profit after a rebound. Markets do not move as a whole.

ETFs and large holders change the circulation of BTC

When viewed across years, the reduction in reserves becomes more meaningful. Bitcoin's market structure is very different from 2020 or 2021. U.S. spot ETFs currently hold large amounts of BTC. Companies have also accumulated considerable reserves. As of the end of September, Strategy, the largest publicly listed company holder, had 847,666 BTC after spending approximately US$143 million on 1,665 bitcoins. These bitcoins are not used to supplement the exchange's daily order book, and they can remain frozen for long periods of time.

Individual investors also resumed buying. In the third quarter, they cumulatively purchased approximately 107,000 BTC units, while funds and ETFs temporarily reduced their positions. The return of capital inflows into ETFs in September changed the picture again. This is probably the most interesting part of today's market: Several classes of buyers can take turns without the number of bitcoins on the exchange continuing to rise. This naturally fuels the idea of a "supply shock." This scenario is well known: the maximum supply of bitcoins is 21 million. Some bitcoins are lost or inactive for years, while others are stored in ETFs, corporate vaults or long-term wallets. If the quantity available on the exchange dwindles and demand rises rapidly, buyers theoretically have to offer higher prices to find sellers.
