I think people don't believe the alt season is right now, so they are waiting a new fall to make a huge buy.
Maybe in 2 months we will have another alt season !
Yes, I agree wit you because most people believe the market will still dip a bit and they will prefer to buy the altcoin when the price is lower than it is now that is why the price of altcoin are no reacting to the bitcoin pump because the price of a coin is dependent on the rate of demand and supply. I am sure when people pump the price of altcoin, then there will be positive rise in the price.
