You brought down only bitcoin, but the other coins do not look very good either. Influenced and the withdrawal of whales of their capitals and various global news, this added to the speed of the fall. The main thing is that everything returns to its place.
Not just bitcoin, almost all coins have a tremendous decrease. Bitcoin is very influential because when the bitcoin price decreases then it will greatly affect the decrease in altcoin prices. But just calm down because at this time a lot of coin that get green, the price has increased and returned as before. Well now we also have to maintain the consistency that is owned by all coin because then we can reach a price range that is much better than the current price. With the increasing confidence of people towards cryptocurrencies, the better the price that will be achieved later.
