Deciding to sell at a loss is a personal decision and it is the same as a person who wants to decide to take a profit when there is a spike in the price of the coin he is holding, so it really doesn't matter as long as his decision can be very right.
Decision-making like this of course has gone through many considerations, we can't judge someone's decision to sell at a loss considering the level of someone's compromise on a loss is different, moreover those who have small capital in investing, the losses that occur are felt and this greatly affects the mental, will be different from those who have large capital, they will actually buy more assets that they consider potential because it will increase the profits they will get.
