If you see, the price of Altcoin went up very high in early 2018 and then the price of Altcoin fluctuated in 2019.
Now in 2020, people are expecting the price of Altcoin to go up. If the price of Altcoin goes too high then it will be very difficult to buy.
Some people say that cryptocurrency is a digital currency, we cannot calculate its value because we cannot accurately estimate the value of cryptocurrency / Altcoin. We can say that when people give bad news about cryptocurrency, people get upset that they sell their currency.
It can be but can't say that all altcoins will soar this year, and quite to think that those abandoned altcoins will remain the same.
I believe this year is full of surprises, it might be another bullish market as halving will help to the market lifted up. But of course, we shouldn't have to rely on halving and not too confident enough that everything will run through good this year still, we suffer dumps by then.
