#数字货币市场洞察 Ethereum's upgrades have become increasingly frequent lately, and many people are closely watching the mainnet's subsequent performance. As the foundational asset of the ecosystem, $ETH often triggers shifts in overall market sentiment whenever there is a breakthrough at the technical level.

Interestingly, when major coins strengthen, ecosystem-based public chains like $BNB and $SOL also start to become active. History tells us that the upgrade cycles of mainstream coins are often accompanied by rotation opportunities for altcoins—commonly known as "altcoin season."

Looking at market sentiment now, there do seem to be some early signs. Mainstream narratives are upgrading and innovating, with funds gradually flowing into various innovative projects and ecosystem tokens. This kind of market rotation usually needs a triggering event, and Ethereum's technical progress is undoubtedly a strong catalyst.

Of course, how long the altcoin season can last will depend on whether the fundamentals of larger markets like Bitcoin remain stable. But at least based on current signals, keeping an eye on public chain ecosystem projects with real progress could reveal quite a few opportunities.
