Despite Bitcoin's strong performance, altcoins failed to follow suit and fell instead. The reasons for this phenomenon include:

Fund flow: Bitcoin's strong performance attracted a large amount of capital inflows, resulting in capital outflows from altcoins. Investors prefer to concentrate their investments in Bitcoin rather than diversify into altcoins.

Market sentiment: The current market sentiment is relatively cautious, and investors choose to hedge in the face of Bitcoin's strength and reduce their investment in altcoins.

Token unlocking: The unlocking of a large number of tokens in the market and the issuance of new coins have put pressure on altcoins, increased market supply, and suppressed price increases.

Project quality: There are many projects of varying quality in the altcoin market, lacking practical applications and innovation, which has led to a decline in investor confidence.
