Currently, Bitcoin's dominance in the crypto market is 56.50%, and the emergence of Altseason is usually accompanied by a decline in Bitcoin's share. Ethereum plays an important role in this process by monitoring the Bitcoin to Ethereum trading ratio, tracking the Altcoin Season Index, and using indicators like RSI. Investors can effectively identify Altseason and seize investment opportunities. At the same time, increased participation from retail investors has brought market volatility, and investors should be cautious about the high risks of emerging tokens, finding a balance between return and risk.
