How Can a Perpetual Swap Contract Be Used to Bet on a Coin’s Potential Failure Due to Double-Spending Risk?
A perpetual swap is a type of futures contract without an expiry date. A trader who believes a coin is highly susceptible to double-spending and will eventually crash can open a short position on the coin's perpetual swap.
If the attack occurs and the price collapses, the short position will be highly profitable. The funding rate mechanism ensures the perpetual swap price stays close to the spot price, making it an efficient tool for long-term bearish bets.
