â ď¸đ° Expert: Bitcoin Faces $8B Attack Risk â Ethereum Called "More Secure" đ
Duke finance prof Campbell Harvey says a 51% attack on Bitcoin is no longer just theoretical. Thanks to derivatives, an attacker could actually profit from crashing BTC đ
Crypto Twitter fired back hard đ
đ The $8B Attack Theory
Harveyâs claim on Wolf of All Streets podcast đď¸:
âśď¸ Old logic: 51% attack = spend billions on mining, destroy BTC, lose everything đ¤Ą
âśď¸ New logic: Short BTC on derivatives first â attack â price crashes â profit from the short đđ¸
The math:
âśď¸ âź$8B cost to attack = 0.5% of BTC market cap Grok estimate:
>$10B in mining rigs + $1.3M/hour in electricity âĄ
âśď¸ Would need offshore platforms â blatant market manipulationHarvey calls it a risk management exercise, not a prediction.
đ Why Ethereum Is "Safer"
âśď¸ Harvey says this doesn't work on Ethereum post-Merge âď¸
âśď¸ To attack PoS ETH you need >50% of liquid ETH supply to control 1/3 of staked ETH.
âśď¸ Buying that much would drive prices up during the attack â kills the short-selling plan đ
âśď¸ He also slammed BTC as too volatile to be a safe haven or store of value.
đŁď¸ Bitcoin Community Pushes Back
X reactions were mostly dismissive:
âśď¸ David Levenson: "Fundamental misunderstanding of how derivatives work"
âśď¸ PrivateCoSaylor: Social consensus could reject attacker blocks â makes it self-defeating
Biggest concern raised đ:
âśď¸ What if profit isnât the motive? A nation-state or short seller might accept losses just to damage Bitcoin regardless of cost.BTC was trading near $62,000 after slipping to $61K last week on US-Iran tensions đ
Bottom line đĄ:
âśď¸ Derivatives + mining power = new attack vector theory. But economic + social defenses + detection risk make it unlikely. ETHâs PoS model changes the game entirely.
