Can a Futures Contract on a PoS Token Be Used to Profit from a Successful Long-Range Attack?

Yes, a futures contract on a Proof-of-Stake (PoS) token, particularly a short position, could be used to profit from a successful long-range attack. A successful attack would severely damage the network's credibility and likely cause a massive price crash.

By entering a short futures contract before the attack is revealed, the trader can profit from the decline in the token's value. This is a form of speculation on systemic risk, but the difficulty of executing and predicting a successful long-range attack makes it a high-risk trade.
