Altcoin selling pressure on spot exchanges has reached a five-year high, according to CryptoQuant analyst IT Tech. The market has experienced net selling for 15 consecutive months, marking a significant downturn for altcoins excluding Bitcoin and Ethereum. The cumulative buy-sell volume difference for these altcoins has hit its lowest negative value since data tracking began in 2020. This trend follows a period in early 2025 when the buy-sell volume difference approached near-flat levels before sharply turning negative. The continued decline highlights ongoing challenges in the altcoin market, as investors remain cautious amid broader market uncertainties.
