Expert: Bitcoin Faces $8B Attack Risk, Ethereum More Secure

A Duke University finance professor, Campbell Harvey, has stated {that a} 51% assault on Bitcoin, lengthy dismissed as a theoretical train that will solely destroy worth for whoever tried it, has quietly grow to be one thing an attacker might revenue from due to at this time’s derivatives markets.

However, many BTC supporters dismissed the declare made through the July 12 episode of Scott Melker’s Wolf of All Streets podcast, arguing that it ignores the sensible financial limitations that will probably cease such an assault.

Derivatives Have Changed Bitcoin’s Risk Profile

According to Harvey, a 51% assault, the place a single entity features the bulk management of the Bitcoin community’s hash energy, has at all times been technically potential however made little financial sense. This is as a result of an attacker would wish to spend billions of {dollars} on mining {hardware} however would solely find yourself destroying the worth of the asset that they had simply compromised.

“Why would you spend billions investing in mining tools, take over the community, however the value of Bitcoin collapses to zero?” Harvey posited. “So you spend all that cash and get nothing?”

But now, he believes that equation has modified, provided that spinoff markets carry sufficient liquidity for an attacker to brief BTC earlier than launching an assault and revenue as the worth falls.

“The distinction at this time is the derivatives markets,” he advised Melker. “What you wish to do is concurrently through the assault take a brief place on Bitcoin, and with a brief the best final result is that if the asset goes to zero.”

The professor did level out that the commerce must happen on offshore derivatives platforms because it amounted to blatant market manipulation. In his analysis paper titled “Gold and Bitcoin,” he estimated that such an operation would value about $8 billion, which is roughly 50 foundation factors of BTC’s whole market worth, though he framed the situation as a danger administration train and never a prediction, arguing that buyers ought to take into account each credible menace as a substitute of dismissing uncomfortable prospects.

When requested the identical query, Grok estimated that anybody seeking to perform such an assault would wish to spend greater than $10 billion on mining machines and about $1.3 million in electrical energy prices each hour. It additionally famous that any try would almost certainly be detected instantly.

Interestingly, Harvey doesn’t suppose the identical situation can work on Ethereum. According to him, since Ethereum switched to proof-of-stake, an attacker has to accumulate greater than half of the liquid ETH provide to regulate one-third of all staked Ether, which might quickly drive costs greater through the try and remove the short-selling alternative he described for Bitcoin.

The educator’s criticism of Bitcoin went past its community safety, as he argued that the OG cryptocurrency is just too risky to qualify as a protected haven asset or dependable retailer of worth. He stated that value swings have stayed high even after years of market progress and deeper liquidity. At the time of writing, BTC was buying and selling close to $62,000 after slipping to close $61,000 final week following the renewal of hostilities between the US and Iran.

Bitcoin Community Pushes Back

The response on X to Harvey’s interview was largely dismissive, with market watcher David Levenson calling the professor’s take “a elementary misunderstanding of how derivatives work.” Another listener, PrivateCoSaylor, argued that Bitcoin’s social consensus might reject blocks produced by an attacker, making the technique economically self-defeating.

However, there have been those that aired totally different considerations, together with pseudonymous dealer Toni, who noted that whereas the entire argument rested on revenue being the motive, the identical wouldn’t maintain if a nation-state or brief vendor merely wished Bitcoin to fail no matter any losses they incurred.
