The potential crash is linked to historical trends, with analysts emphasizing August 2025 as a critical period for risk. Analysts like Benjamin Cowen have flagged signs from past cycles indicating a possible market downturn. This coincides with heightened leverage in assets like Ethereum and Dogecoin, as well as concerns regarding liquidity risks highlighted by PANewsLab.
