I would say that's it's natural to see such dumps after a long pump that happened during the last two days. Some traders try to close their short positions and get a profit from such volatility. But I prefer just to wait, because it's too risky for me. I expect that the price will go up again tomorrow.
This situations is very normal that all cryptocurrencies incounter dumping and pumping there price value. It's depends upon the demand and supply in the market. So as we an see now the price of all cryptocurrencies are slowly to moving up. But we can not predict how long it goes. Maybe tomorrows it going to red agin or maybe there is a continuously improvement of moving up the price of all cryptos.
