It seems that the price of Altcoin has stopped in one place and is getting lower. If the price of Altcoin stays at that fixed point, then it is very difficult for the price of Altcoin to fall. If the price of Altcoin now becomes too high, then people will start buying more and more, which will cause the price of Altcoin to go up. Is that right?
The price of cryptocurrencies does not stay stable, unless it's a stable coin. Any other coin which is not a stable coin does not stay stable. There might be times when they are fluctuating much, but it doesn't happen for long and they will start fluctuating up and down again. Most of these altcoins you're seeing follow the price movement of bitcoin (correlation) and when the bitcoin is going up they do the same, same thing with the opposite. If you do check the price chart you will notice that they are all a little bit similar to each other.
