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).

According to Lookonchain, on April 17, Bitcoin ETFs saw a net outflow of 2,050 BTC valued at approximately $172.33 million. Fidelity alone accounted for an outflow of 1,353 BTC, amounting to $113.75 million, while holding a total of 194,273 BTC worth $16.33 billion.

According to IntoTheBlock, net exchange outflows reached nearly 19,000 BTC, primarily driven by a significant 21.75k BTC outflow from Bitfinex.

Such large outflows can indicate a decrease in selling pressure on exchanges, impacting short-term price movements.
