Between mainstream and mainstream, and between mainstream and sub-mainstream, there is a seesaw. When strong stocks pull back, funds will cluster together to support other mainstream and sub-mainstream stocks. If you see the activation K, don't hesitate too much; there is definitely cost performance to be had.
A major warning point: For some small altcoins, if the exchange with the largest position is not Anan/OK/bybit, be wary of data manipulation. Not being misled into investing is a respect for money. (The few altcoins that collapsed during night trading have common characteristics in the exchanges with the largest futures positions; seeing through it without speaking out.)
