Duke University professor Campbell Harvey suggests that a costly $8 billion 51% attack on Bitcoin could become financially viable by pairing mining control with large short positions in Bitcoin derivatives. Traditionally, such attacks were seen as economically irrational because the attacker would lose value as Bitcoin's price collapsed. However, Harvey argues that derivatives markets allow attackers to profit from the price drop triggered by the attack, offsetting mining costs. While the scenario remains theoretical and faces practical barriers like detection and coordinated defenses, it raises new concerns about Bitcoin's security model and the economic incentives created by modern financial markets.
