In my opinion. nobody has been able to predict the rise in coin prices. Unless it is done by the Pump and Dump community. That was the predicted price lasted only a few minutes. after that the price will come back down.
However, if you want to know the price change from Altcoin. You simply monitor the price of Bitcoin. Because in general the price of Altcoin will drop when the price of the bitcoin rises. and after the bitcoin price stabilizes, altcoin prices begin to rise one by one.
