yes, it can be predicted.
two tips
1º After every pump, there will be a dump. Traders usually sell their coins short-term after getting from 5 to 10% profit. the faster they get it, the faster they sell. if prices go up while having gotten their 10%, they will hold a bit more till the price stops increasing for 6 - 12 hours.
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.
