He highlights that perps provide high leverage and deep liquidity, making them essential tools for active traders seeking to hedge or amplify positions. The popularity of perpetual swaps on major crypto exchanges has significantly increased trading volume and volatility, impacting both short-term price movements and long-term market dynamics. Henri emphasizes that understanding how perps function is critical for traders aiming to manage risk and capitalize on trading opportunities in the evolving digital asset landscape (source: @HenriArslanian on Twitter, May 13, 2025).
