Maybe it will come back again. But not all altcoins will come back. To my mind, only the top 100 altcoins will return in 2020, and all the rest will die because it doesn't have any benefit.
yes now it has seen the movement of several altcoins began to rise in price slowly (only altcoins whose projects are clear), and out there are many more altcoins that are not clear and there is no movement at all even the volume is just starting to disappear from the exchanger
