Nothing is sure in this market, no one can know exactly what will happen. We can only predict and pray for a bright future. Let's look back 2017, We have seen many amazing prediction for the price of bitcoin/ altcoins. And now, almost investors have lost their fund. LOL 
I remember many people in last year, in July, they said that Bitcoin die and it would not grow anymore and bitcoin do not need to anyone and they were sold their assets. The same thing is happening now
