I don't know how and where you people are saying altcoin pump would begin from next year, to me altcoin pump has started begining from when bitcoin created new ATH. Realistically we can see lot of altcoin pumping severely such as Ripple, ETH, BNB and many other coins has gained interest in the market.
Maybe if we are talking of next year then it's the general bull run which I know the bull run has started already.
I will not disagree with you that altcoin pumping has not happened yet, yes altcoins were also pumped along with bitcoin pumping. But when bitcoin dumped for correction, altcoin market immediately dumped a lot but even after bitcoin recovered, the altcoin market was struggling to recover.
The altcoin market was in a bad state before this November, but it is currently heading in a much better direction, and I think most people are saying that the altcoin season will maybe start next year. Altcoins have pumped but not much, most of the big coins like Ethereum have not been able to reach their last all time high price. So even though it seems like the altcoin season has started now, I think the real alt season will start in the first quarter of next year.
