Saldo da exchange de BTC atinge o menor nível em sete anos, análise do impacto na oferta e visão geral dos dados on-chain

On-chain data shows that the reserves of Bitcoin on major global exchanges have fallen to approximately 2.447 million BTC, reaching a new low since 2018. This change is not a short-term fluctuation but a direct reflection of the ongoing evolution of supply and demand structures. When sell-side supply becomes increasingly scarce while buy-side demand remains steady, is the market approaching a “supply shock” narrative?

What is the current level of BTC holdings on exchanges

As of 2026-04-27 Beijing time, according to Coinglass data monitoring, the total BTC balance across cryptocurrency exchanges has dropped to about 2.447 million. Looking back over the past week, the market experienced a net outflow of 15,952.91 BTC, with outflows continuing to expand. This figure indicates that since the peak in 2024, nearly one million BTC have flowed from public trading platforms into non-liquid or long-term storage environments. The persistent shrinkage of exchange balances signifies that a large amount of Bitcoin is shifting from a “potential sell-off” to “reserve assets.” Based on inventory flow, several major exchanges contributed most of the net outflows during the sample period, and on-chain data largely rules out the possibility of anomalies from a single entity, pointing to a more widespread transfer intention.

Why is Bitcoin continuously flowing out of exchanges

The direct reason for the decline in exchange holdings is that outflows have consistently been significantly higher than inflows, but the underlying driving forces are more profound. Institutional spot ETFs have become an important channel for absorbing liquidity. Take BlackRock’s IBIT as an example; this product absorbs about 2,100 BTC daily on average, far exceeding the daily mining output (about 234 BTC), creating a typical supply-demand divergence. Meanwhile, corporate treasury allocations have also become another key force for liquidity absorption. Strategy has accumulated 94,470 BTC by 2026, equivalent to 2.2 times the miner’s output during the same period, meaning that even after absorbing all new supply, additional liquidity must be drawn from exchange reserves. Beyond institutional levels, geopolitical volatility and the advancement of the US “Clear Act” have also touched on large holders’ asset security considerations, triggering some long-term holders to transfer assets into cold wallets.

Who are the main buyers in the current market

While exchange supply continues to decrease, the buyer structure is undergoing significant changes, and it is not dominated by retail investors. Data from on-chain analysis platform Santiment shows that wallets holding between 10 and 10,000 BTC—often considered “key stakeholders”—accumulated about 95,000 BTC from February to April 2026, with this accumulation pace showing a high correlation with the approximately 22% price rebound during the same period. Since April 10, this group has added an additional 40,967 BTC, worth over $3.1 billion. Compared to the cooling enthusiasm of small-scale holders, the continuous entry of large holders has formed a clear wealth-differentiated buying structure. Regarding the whale ratio on exchanges, about half of all inflows come from whale-sized transactions, and this ratio has remained around 0.5 for several months, fundamentally different from the short-lived, sharp spikes typical of distribution scenarios.

How does institutional capital inflow intensify liquidity tightening

In addition to direct coin holdings purchases, institutional funds continue to inject liquidity into the market through the spot ETF channel. As of the end of April, 12 US spot Bitcoin ETFs recorded nine consecutive days of net inflows, with a single-day net inflow exceeding $223 million on April 23, and total monthly inflows reaching $2.43 billion, demonstrating steady accumulation rather than short-term quick inflows and outflows. Such persistent inflows often provide more stable structural support for price ranges because ETF buying involves transferring underlying Bitcoin from hot wallets on exchanges to custodial accounts, forming near-irreversible liquidity locks. Furthermore, ETF holders tend to hold long-term. BNY Mellon states that ETFs are increasingly used as long-term asset allocation tools rather than short-term trading vehicles. This shift from “trade-oriented” to “reserve-oriented” behavior is a key variable behind the structural decline in exchange holdings.

Does miner selling constitute an oversupply on the supply side

In the ongoing consumption of exchange reserves, another variable to watch is miner holdings. As of April 25, Bitcoin miners’ total holdings fell to about 1.803 million BTC, reaching a one-month low. In Q1 2026, listed mining companies sold over 32,000 BTC. Miner holdings have continued a cumulative reduction trend of over 61,000 BTC since 2024. While miner selling adds to circulating supply, the buying power to offset this pressure is more concentrated. Data shows that miner sales are routine to cover operational costs, and their scale still differs significantly from institutional and corporate net increases, so they are insufficient to reverse the downward trend of exchange reserves.

Does the “supply shock” narrative have fundamental support

The decline in exchange supply is not a new concept, but the current structure differs from previous cycles mainly due to the maturity of institutional custody systems and the institutionalization of participants. The decline in exchange balances at the end of 2020 led to the 2021 bull market, when institutional participation was much lower than today. Now, Bitcoin deposited into institutional custody accounts and ETF products is almost permanently locked—unless there are extreme systemic liquidations, these funds are unlikely to flow back to exchanges to create immediate selling pressure. Data on average order sizes for spot orders has consistently pointed to whale-sized orders dominating the market since October 2025, throughout the entire price correction process and current price range. From a supply-demand fundamental perspective, the persistent reduction of seller reserves combined with ongoing buyer demand provides data support for the supply shock narrative, but does not offer a definitive forecast of price direction. The shrinking supply side implies higher price elasticity under similar buy-side shocks, but the fundamental price range still depends on macro liquidity, risk appetite, and other multi-dimensional variables.

What risk signals in the market contradict the supply tightening narrative

The reliability of the supply tightening narrative needs to be cross-verified with other market signals. Some indicators currently show divergences worth noting. The 8-hour average funding rate across the Bitcoin network has turned negative, indicating that leveraged traders are cautious in the short term. Additionally, miner holdings have fallen to a monthly low, suggesting that selling from this supply source continues. Moreover, although total exchange volume has decreased, divergence in whale ratios across some exchanges hints that some large whale accounts are still depositing assets onto platforms.

From a macro and market environment perspective, global economic uncertainty remains unresolved, and the pace of monetary policy shifts is variable, which could exert pressure on the valuation of risk assets. This means that even if BTC is positioned within a supply-side tightening narrative, the effective realization of a supply shock heavily depends on synchronized demand-side support. Without demand-driven factors, liquidity exhaustion could amplify downward price elasticity, creating a feedback loop. Therefore, the supply-side narrative should be evaluated together with demand-side evidence, as relying on a single indicator is insufficient for a comprehensive forecast.

How might changes in the supply structure influence the future operational framework of the market

The ongoing downward trend in exchange reserves is transforming the operational framework of the Bitcoin market. From a trading mechanism perspective, as liquidity pools shrink, order book depth diminishes accordingly, and each new buy order’s impact on price may increase. From a holdings structure perspective, the rising proportion of long-term holders and institutions extends the turnover cycle, further clarifying the de-spekulation trend. The continuous outflow of exchange balances essentially reflects a gradual shift of crypto assets from “transaction medium” to “reserve assets,” fundamentally different from the cycles before 2020. These changes do not involve arbitrary predictions or judgments about price paths but indicate that the market’s underlying operational rules are evolving beyond short-term price fluctuations. Comparing the 2024 high point (over 3.2 million BTC) with current reserves, a net outflow of about 1 million BTC marks the conclusion of a nearly two-year structural migration. As exchange reserves approach a new lower equilibrium, market participants may shift focus from short-term trading to longer-term supply-demand matching logic.

Summary

Bitcoin reserves on exchanges have fallen to 2.447 million BTC, the lowest since 2018. This trend is driven by multiple structural forces: continuous absorption by institutional spot ETFs, laddered increases in corporate treasuries, and a shift towards self-custody by investors. On the demand side, whale addresses continue to accumulate, with wallets holding between 10 and 10,000 BTC adding about 95,000 BTC from February to April 2026, maintaining a buyer presence amid supply shortages. While miner selling is a source of supply, its scale is orders of magnitude smaller than institutional accumulation. Persistent ETF inflows also provide a stable demand foundation. These fundamental changes are not short-term price predictions but are reshaping the long-term supply-demand structure of the market. Meanwhile, negative funding rates and macro uncertainties suggest that the supply shock narrative involves multiple variables that need to be considered. Market participants should conduct multi-dimensional data analysis rather than rely on single indicators for judgment.

FAQ

Q: Does the decline in exchange BTC reserves mean the market is about to rise?

A: Not necessarily. The decline in reserves reflects reduced liquidity available for trading. If demand remains steady, it could support upward price movement. However, price direction also depends on demand strength, macro environment, risk appetite, and other factors; a single indicator cannot determine the market trend.

Q: What is a “supply shock”? Why is it being discussed more recently?

A: A “supply shock” refers to a significant reduction in the available Bitcoin supply for trading, making any new demand potentially have an outsized impact on price. Currently, exchange reserves are at their lowest since 2018, combined with ongoing institutional buying, which has led to increased discussion of this term.

Q: Will institutional ETFs and corporate accumulation reverse?

A: Historically, ETF inflows and outflows depend on market conditions and investor redemption willingness. However, the underlying assets of Bitcoin ETFs are usually stored with professional custodians, and unless there are systemic liquidations, these Bitcoins are unlikely to flow back to exchanges to create selling pressure, giving them a certain resilience.

Q: Will miner selling impact the strength of the supply shock?

A: Miner selling does add to supply but is constrained by operational costs and mining economics. Currently, institutional accumulation far exceeds miner output, so miner behavior is more a variable on the supply side rather than a decisive factor.

Q: What on-chain indicators should be monitored to track the development of the supply shock?

A: Key indicators include exchange net flows (daily changes in exchange Bitcoin balances), whale address holdings, daily ETF net inflows, and long-term holder supply changes. Cross-verifying multiple indicators provides more reliable insights than relying on a single metric.
