Two simplest and most straightforward logics for being optimistic about Ethereum:

1. Vitalik is one of the very few founders driven by technical ideals rather than commercial interests—his motivation for promoting Ethereum stems from a belief in decentralized technology, not short-term arbitrage;

2. Ethereum has consistently adhered to the core principles of decentralization, maintaining its benchmark status in the public chain field in terms of censorship resistance and security.
