According to Santiment, Ethereum's exchange supply has dropped below 4.9% for the first time in over a decade, while Bitcoin's exchange supply has fallen to 7.1%, the lowest since November 2018. Over the past five years, there are 1.7 million fewer Bitcoins and 15.3 million fewer Ethereum tokens held on exchanges. This significant outflow from centralized platforms indicates reduced short-term selling pressure and rising investor preference for long-term holding, which are historically bullish on-chain signals for price action. Traders should monitor these trends closely, as lower exchange reserves often precede increased volatility and potential price surges in the cryptocurrency market (Source: Santiment, Twitter, May 19, 2025).

According to Cas Abbé, Bitcoin exchange supply has decreased to just 2.5 million BTC, marking the lowest level since Q3 2018. This represents a reduction of 500,000 BTC since Q4 2024. Recent disclosures from Fidelity indicate that institutional investors are actively purchasing and withdrawing Bitcoin from exchanges, intensifying the existing supply squeeze. For traders, the declining exchange supply combined with increasing institutional demand creates a bullish environment for BTC price action (Source: Cas Abbé on Twitter, April 27, 2025; Fidelity Institutional Reports).
