Recent research shows that the threat of a "51% Attack" faced by Bitcoin is severely underestimated by the market, with attackers needing only about $6 billion to destroy Bitcoin. On October 9, Campbell Harvey, a finance professor at Duke University, warned in the latest research that although Bitcoin and gold are both seen as favorites in the "currency devaluation trade," the risks faced by Bitcoin far exceed those of gold. Attackers can gain control over the Bitcoin network within a week by purchasing hardware worth $4.6 billion, investing $1.34 billion in building data centers, and incurring approximately $130 million in electricity costs each week.
