The ecosystems of Bitcoin and Ethereum have evolved significantly. Bitcoin's ecosystem remains focused on its use as a store of value and digital currency, with increased adoption in areas like payments and remittances. The Bitcoin Lightning Network has expanded, enabling faster and cheaper transactions. Ethereum’s ecosystem has diversified with the rise of decentralized finance (DeFi) and non-fungible tokens (NFTs). Ethereum's transition to Proof of Stake (Ethereum 2.0) has attracted more developers, improving scalability and sustainability. Both ecosystems now see growing institutional interest, and more projects are building on these platforms, driving innovation in the blockchain space.
