#Quick News# Golden Finance reported that Bitwise CIO Matt Hougan said on Twitter that Bitcoin ETF holders should consider adding an Ethereum ETF to their portfolios. The reasons he gave include: 1. Diversified investment to prevent one asset from falling out of favor or being swallowed up by another; 2. Bitcoin and Ethereum are essentially different. The former aims to be a "better currency", while the latter is designed for "programmable currency" and supports blockchain applications such as stablecoins and DeFi; 3. Historical performance shows that the two assets work best when they are balanced in the portfolio. However, he also pointed out the main reason why investors may still want to keep Bitcoin - Bitcoin may become the dominant new form of "currency".
