ETH's leading rise may be a signal of the upcoming altcoin bull market to a certain extent, but it cannot be absolutely assumed that ETH's leading rise means the altcoin bull market. The following is a specific analysis:

The positive impact of ETH's leading rise on altcoins

Fund drainage effect: As the second largest cryptocurrency in terms of market value, ETH's price increase attracts more funds to flow into the crypto market. When ETH continues to lead the rise and the market's expectations for it continue to improve, it will attract more investors to pay attention to the entire crypto field, and some funds will overflow from ETH to the altcoin market, providing a financial basis for the altcoin bull market.

Ecological driving effect: ETH's ecosystem is huge, including DeFi, NFT and other fields. ETH's leading rise will drive the development of its ecological projects. Good news such as the upcoming launch of ETH's pledged ETF will increase the popularity and value of the entire ecosystem, and related altcoins will also benefit, thereby driving the overall altcoin market to improve.

Market sentiment boost: ETH's leading rise often increases the confidence and optimism of market participants, making investors more positive about the entire crypto market, thereby increasing investment interest and demand for altcoins and driving altcoin prices up.
