I do not think that people have lost interest in the Altcoins, in any case, those who are in the crypto market for a long time. Previously, the Altcoins showed much more rapid growth and good profits. But today top coins have become too "heavy", too much money is invested in it, too many people want to sell the purchased coins at no loss. This leads to the fact that the price is extremely difficult to grow in such conditions.
Only people who don't know crypto are losing interest because prices are falling. falling prices are natural, so why aren't you interested because prices fall? even though the price will recover after that, actually the falling price is an opportunity right? I am not sad or even lose interest, because I understand it as market dynamics
