this is very funny, in my opinion most of the dumper are not those who buy bitcoin at the price of $ 19k but this is a game of price and the market is being manipulated.
everyone has different conditions, so when people sell at a cheap price, there will be a reason. well, maybe you don't have an urgent need so you can still hold the assets you have, and wait for the price to be even higher.
It is true that for individual cases everyone has different financial consideration and their problems. So accordingly they take decisions even at times when they know it is better to hold than to sell but immediately when some one require money need to sell the coins and suffer losses. I hope atleast people do not sell in panic mode which could lead to further problems.
