In this market, I would not sell anything
I will only say be wise to know the right thing to do. There are some coins that are not worth holding even irrespective of the market condition. Watch out because exchange might start delisting that coin you so much believe in because they have gone too low as a result of the market condition. So kindly take a good look and Know what to buy, sell and HODL for bull run which isn't far from now.
