Recently, altcoins have been growing too aggressively; a pullback will make the market healthier.

When Bitcoin rises, altcoins do not rise; when Bitcoin falls, altcoins fall sharply.
An unusual phenomenon is occurring in the current bull market: although the price of Bitcoin is rising, many altcoins are experiencing declines, with some altcoins plummeting by around 40%. The reasons for this situation can be analyzed from the following aspects:
1. Change in market structure
The dominance of Bitcoin has increased: In this bull market, Bitcoin's market capitalization share has significantly risen, leading to increased attention and investment enthusiasm for Bitcoin, causing more funds to flow into Bitcoin rather than altcoins. This increased dominance suppresses the performance of altcoins.
