I think, ETH and BTC have significant future growth potential, but they have different characteristics and roles in the crypto ecosystem. Ethereum is well-known as a platform for decentralized applications and smart contracts, while Bitcoin has become the most famous and largest cryptocurrency. The growth of both will be influenced by factors such as technology development, use cases, competition, external factors and institutional adoption. Investing in crypto always involves risk, and there are no guarantees or firm predictions about the future growth of ETH and BTC.
