According to Cas Abbé, August 2025 is seeing a significant increase in altcoin outflows from exchanges, mirroring the trend observed in July. Abbé notes that altcoins are being withdrawn from exchanges rather than deposited, which typically indicates that investors are choosing to hold rather than sell their assets. This pattern follows Bitcoin's recent strong performance, suggesting increased confidence among altcoin holders and potential tightening of available supply on trading platforms. Such developments are noteworthy for traders monitoring market liquidity and sentiment shifts in the altcoin sector. Source: Cas Abbé

According to IntoTheBlock, both Bitcoin and Ether experienced a robust week marked by a notable rise in overall transaction fees and significant net withdrawals from major exchanges. These metrics indicate heightened on-chain activity and suggest continued accumulation by investors, which are key trading signals for bullish momentum in the crypto market (source: IntoTheBlock, April 25, 2025). Traders should monitor these trends as they often precede price rallies and shifts in market liquidity.
