May 2021 Crash

Volatility

The May 2021 Crash, impacting cryptocurrency markets, originated with significant selling pressure in Bitcoin and Ether, quickly propagating through the broader altcoin ecosystem. Leveraged positions across multiple exchanges experienced cascading liquidations, exacerbated by imperfect on-chain data and limited circuit breakers. This event highlighted systemic risk inherent in highly leveraged crypto derivatives, particularly perpetual swaps, and the speed at which information asymmetry can trigger market instability. Subsequent analysis revealed a correlation between the price decline and large holder activity, prompting scrutiny of market manipulation potential.
