How Can a Miner Hedge against the Risk of a 51% Attack on a Cryptocurrency They Hold?

A miner can hedge against the risk of a 51% attack, which would likely cause a massive price drop, by taking a short position on the cryptocurrency. This can be done by selling a futures contract or buying a put option.

If the attack occurs and the price plummets, the profit from the short position or the put option would offset the loss in value of their mined coin holdings.
