Bitcoin breaks new highs, but the market is not too excited, so it's definitely not the top; it's only when many people start to resist and go long that it will be the top. Altcoins may still be down, but the habit of altcoins is that a two-month increase offsets a three-year decline; bulls are short and bears are long.
When the trend comes, all you need to do is "wait"
Money is made by sitting and waiting, the wind blows in.
Thinking from the perspective of the market makers and project parties, why do they only dare to come out and make a fuss, brag, and talk narrative when Bitcoin hits new highs?
So, you don't need to worry about there being no altcoin season.
There’s nothing new in the financial markets; human nature never changes.
