$ETH Increase ETH Allocation: For investors, the rise of ETH/BTC may be a signal indicating that increasing the allocation to Ethereum could be more favorable. Especially driven by Ethereum's technical updates (such as the transition to PoS consensus mechanism) and ecological development (such as the prosperity of DeFi and NFTs) [^5^]. Hedge Risks: Investors can hedge risks by adjusting the holding ratio of ETH and BTC. For example, when ETH/BTC rises, reduce Bitcoin holdings and increase Ethereum holdings to balance the portfolio [^6^].
