The next step for altcoins, alongside the evolution of blockchain technology and market maturation, is expected to be diversification and innovation. First, the growth of DeFi (decentralized finance) and NFTs (non-fungible tokens) is expanding the use cases for altcoins. Next, the adoption of environmentally friendly consensus algorithms (e.g., proof of stake) is progressing, leading to improved energy efficiency. Additionally, the clarification of regulatory frameworks will enhance investor confidence and improve market stability. Furthermore, the strengthening of cross-chain interoperability will facilitate the transfer of data and assets between different blockchains. As a result, altcoins will gain more practical use cases and integration with mainstream financial systems will advance.
