What Are the Implications of a 51% Attack for a Coin’s Derivatives Market, Such as Futures?

A 51% attack creates extreme volatility and uncertainty, leading to massive liquidations in the futures market. Exchanges will likely halt trading, and the futures price will crash, potentially trading at a significant discount to the spot price.

This disruption can trigger 'circuit breakers' and necessitate emergency settlement procedures, causing financial distress for leveraged traders.
