Bitcoin's Security Budget Under Scrutiny
The Bitcoin (BTC) blockchain operates on the Proof-of-Work (PoW) consensus mechanism. Critics have raised concerns about its energy consumption and the potential vulnerability of the network. In contrast, Ethereum (ETH) successfully transitioned to a Proof-of-Stake (PoS) model, prompting discussions on whether Bitcoin should follow suit.
Concerns Over 51% Attacks
Anthony Sassano, a prominent crypto analyst, warns that Bitcoin does not maintain a sustainable security budget, making it susceptible to a 51% attack—a scenario where a single entity gains control over more than half of the network's mining hash rate. Sassano highlights that Ethereum's transition to PoS has equipped it with a budget capable of mitigating such risks.
"More people need to understand that the Bitcoin network is quite literally a ticking time bomb. This is not 'fud'—it's the reality of a chain lacking a sustainable security budget."

Counterarguments from Experts
John Galt, Head of Strategy at Stride Zone, disagrees with Sassano's assessment, asserting that Bitcoin's social layer is robust enough to withstand a 51% attack. Galt believes that even with declining block rewards, there remains an incentive for miners and users to secure the network.
"This isn't true, because the social layer of Bitcoin is strong enough to resist a 51% attack. Block rewards may fall, but transaction fees provide continuous incentive to secure the chain."
— John Galt
Current Market Status
As of now, Bitcoin is trading above $63,000. The debate continues on its ability to fend off potential attacks, especially if it were to transition to a PoS mechanism similar to Ethereum's.
