There must be expectations for the market; even if the overall direction appears bearish, it does not affect the continued holding of some altcoins.
This wave of decline is obviously meant to scare people; the probability of a direct crash is extremely low. With the bullish liquidity for Ethereum already cultivated, in order to go lower, they must cultivate bullish liquidity for Bitcoin as well.
There is a high probability of a bull trap appearing here; I believe that the altcoin operators are not fools, and they will see this.
