Great overview of the current state and future prospects of Ethereum. It's interesting to see the challenges faced by Ethereum and the proposed solutions such as Ethereum 2.0 and layer 2 scaling solutions. The emphasis on security and the partnership between Ledger and Ethereum is reassuring for users. It's great to see the focus on the importance of security, especially in the context of hardware wallets. However, further elaboration on best practices for securing Ethereum assets and mitigating risks could provide more value to readers, especially those new to the space.
