yes, it can be predicted.
to tips
1º After every pump, there will be a dump. Traders usually sell their coins short-term after getting from 5 to 10% profit
2º If the price of a coin, or directly the price of BTC stays without increasing for 24 hours, there will be a bear moment, because those people consider that if there is no pump, it's because there will no demand of coins.
Let me guess. If prices don't go up tomorrow, on Friday we will have another travel to hell with ETH very close to 300$ or even lower.
It's not possible unless you have a bunch of coins already.
