The index #altcoinseason is at 84/75 according to blockchaincenter, this level indicates a strong FOMO trend when $BTC surpasses the 100k mark.
However, one can see the index chart making a straight spike from 40 to above 80 points with no balancing adjustment. Such rapid growth means that the altcoin season is coming early and will drop early.
It is natural for there to be both increases and decreases in the financial market, so no one should expect this market to keep rising indefinitely.
