Ethereum continues its upgrade to ETH2 and the move to a proof-of-stake system. Because of the popularity of decentralized finance, Ethereum has the potential to continue to grow. Additionally, the ability to build decentralized apps and the wide adoption of the ERC-20 token standard make Ethereum a likely candidate for long-term viability. Ethereum Classic has been working on upgrading its protocols and blockchain technology to be more compatible with the main Ethereum blockchain. As a result, Ethereum Classic might remain relevant, especially if interoperability between the two chains can be achieved and maintained.
