Bitcoin, Ethereum Tank 7% on Vitalik Buterin's PoS Book Launch Day - Sept. 28, 2025
On September 28, 2025, the cryptocurrency market experienced a significant downturn. Leading cryptocurrencies Bitcoin and Ethereum both fell more than 7%. The unexpected drop coincided with the launch day of Ethereum co-founder Vitalik Buterin's new book on Proof of Stake (PoS).
While the exact cause of the price decline is still under debate, the timing has raised eyebrows. Some analysts speculate that the book launch, while intended to be positive, may have inadvertently highlighted existing concerns or vulnerabilities within the PoS system, leading to market uncertainty and sell-offs.
Vitalik Buterin himself has been vocal about the need for improvements to the Ethereum protocol. In a recent statement, he emphasized the importance of simplification, aiming to reduce its complexity to a level closer to Bitcoin's while preserving its unique functionalities. This call for simplification comes as the Ethereum network faces increasing challenges related to scalability and security.
