Bitcoin exchange balances have dropped to their lowest levels in years, yet the long-standing bullish signal no longer carries the same influence as the market evolves. Blockchain analytics firm Santiment said exchange-held Bitcoin and Ether have fallen to levels last seen in 2017 and 2015.
At the same time, industry executives say institutional custody, spot exchange-traded funds, and decentralized finance have reshaped how digital assets move across the market. As a result, declining exchange reserves no longer provide the same straightforward indication of future price strength.
For years, investors viewed declining Bitcoin balances on centralized exchanges as a positive market signal. Lower exchange reserves often suggested investors moved coins into self-custody instead of preparing them for sale.
According to Santiment, Bitcoin now holds only 6.6% of its circulating supply on exchanges, while Ether stands at 4.3%. The firm described the trend as one of the strongest long-term indicators since fewer coins remain immediately available for selling after months of market volatility.
Santiment also stated that Bitcoin and Ether still account for nearly 66% of the total cryptocurrency market capitalization, based on CoinGecko data. Therefore, the company said lower exchange balances could support the next sustained bull cycle, although it noted current market conditions have not reached that stage.
Mark Zalan, chief executive of GoMining, said prolonged declines in exchange supply have historically appeared before multi-quarter bull markets. Even so, he declined to predict when another cycle could begin, saying accurate timing remains uncertain.
Despite historically low exchange balances, Bitcoin has traded around half of its previous peak value for months. Consequently, several industry participants believe the traditional interpretation no longer reflects the broader market structure.
Eneko Knorr, chief executive of Stabolut, said the market has matured beyond simple exchange balance analysis. He explained that many digital assets now move into staking platforms, decentralized finance protocols, and institutional custody instead of remaining on exchanges.
Bitcoin withdrawn from exchanges often moves into wrapped assets such as WBTC before entering decentralized finance applications. Investors continue trading those assets, using them as collateral or lending them across decentralized markets despite lower visible exchange reserves.
A similar pattern appears in spot Bitcoin exchange-traded funds. When investor demand increases, ETF issuers purchase Bitcoin before placing it with institutional custodians including Coinbase Custody, Fidelity Digital Assets, and BitGo. Investors then trade ETF shares on regulated stock exchanges while the underlying Bitcoin remains outside exchange wallets.

Industry executives also argue that exchange balance data fails to capture Bitcoin's expanding financialization. Coinglass data shows U.S. spot Bitcoin ETFs currently hold about $73 billion in net assets, representing more than 641,400 BTC. Ether ETFs manage roughly $13.7 billion, representing about 7.7 million ETH.
Ben Nadareski, chief executive of Solstice, said lower exchange balances reflect the end of the exchange-custody era rather than a simple bullish indicator. He said assets now move toward regulated custodians or productive on-chain positions instead of remaining on trading platforms.
Historical performance also shows that lower exchange balances do not always lead to higher prices. During 2022, exchange reserves stayed relatively low while Bitcoin prices still experienced a sharp decline.
Even so, Bitcoin accumulation continues across several market segments. Zalan said more than 130 public companies now hold Bitcoin on their balance sheets alongside growing ETF demand.
According to Bitcoin Treasuries, public companies hold about 1,264,579 BTC, while private companies own 281,752 BTC. Government entities control 649,954 BTC, DeFi and related protocols hold 369,595 BTC, and ETFs together with exchanges account for 1,622,533 BTC. The data also shows that treasury companies hold about 7.252 million ETH.
Bitcoin Treasuries further reports that nearly seven million Bitcoins remain in dormant wallets. Combined with institutional and treasury holdings, almost 11.2 million Bitcoins sit outside active trading, representing about 56.5% of the current circulating supply of roughly 20.05 million BTC.
Bitcoin exchange supply remains near multi-year lows, but ETFs, institutional custody, and DeFi have changed how the market interprets the indicator. While accumulation continues across companies, ETFs, and long-term holders, exchange balances alone no longer provide a complete picture of potential market direction.
