According to Michaël van de Poppe, a rollback on Ethereum ($ETH) by any single party could severely damage trust within the entire cryptocurrency ecosystem. This action could challenge the foundational principles of decentralization and create uncertainty about the reliability of the Ethereum blockchain in the future. Such a development would have significant trading implications as trust in the decentralized nature of Ethereum is a critical factor for investors and traders.
