Altcoin exchange inflows have decreased to $1.6 billion monthly, below the annual average of $2.5 billion, according to CryptoQuant analyst Axel Adler Jr. This trend, observed as of June 27, suggests a potential market upswing, as similar low inflow periods historically preceded altcoin market rallies. Previous instances of low inflows, such as early 2023 and mid-2024, were followed by significant market activity.
