Yes, we have seen this type of downfall from 2018 to till date, which many people afraid a lot previously that bitcoin will decrease its price below 1000$. Even now people are predicting the price of Bitcoin will go below 2000$ and this makes many people panic about the current situation, but people should understand it is an opportunity to grab the Bitcoin at low value.
If people can think clearly about the opportunity to buy bitcoin at a low price, they will see that as a great time to buy, but if they panic, they will not see anything except they will know that they will get lost. Right now, bitcoin price back to increase, and many people use this opportunity to sell their bitcoin after they bought it a few days ago.
That is why people still expecting continuous growth of bitcoin price because they already buy a lot of bitcoin at a low price, and they are waiting for the next moment of the increasing of the price.
