BTC and Ether are continually probing for new support levels, but observant frens should notice that a significant portion of altcoins are not following the fall, which is an intriguing signal.

To avoid misleading others, I will say a few words of nonsense. The first scenario is that BTC and Ether hit the bottom and rebound with fluctuations, while altcoins quickly rebound and then welcome another wave of market activity.
The second type is Bitcoin, Ether has fallen again, crashing hard, and altcoins have completely collapsed.
What I am saying is all about possibilities or probabilities; this is a summary of past experiences. In short, the fact that altcoins do not fall together is a positive signal and is worth speculating.
However, a rebuttal to this statement is: "It's just that the mainstream hasn't fallen enough."
