When my tokens are in loss like 80-90%, there is no sense to sell it, because 10-20 % of initial value isn't that much and price can be back, but if you fix loss,
then you lose all chances for rebounce and potential growth.
That is right. There is no point of selling the coins after they have lost most of their value. I am holding only coins that I have a full faith in it and I am not afraid of price drops.
