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.
some altcoin depends on bitcoin when bitcoin price rise
some of the altcoins also get a price increase
bitcoin halving is coming that why we can also expect some rise for altcoin
but the risk is high in my opinion as of now its better to invest in bitcoin than altcoin
