One of the reasons why bitcoin price still go down is because of many people who are selling what they own because they are afraid that they could lose more if they try to hold onto it longer. In these past few weeks the price of bitcoin were stuck around $10k-11k and right now it goes down again probably more people have dump also their bitcoins for the same reason or they are not anymore expecting that it will bounce back higher.
This is not a valid reason in my opinion. Such people had always existed in the past as well and do not have much impact on the prices. Prices going down is actually an encouragement for new investors. Even the current investors can make a good use of this opportunity to increase their bitcoin holdings. However, I agree that we should still do something about the investors who panic to see sudden bitcoin price drops because they must be spreading their negative experiences with bitcoins to their family and friends.
