This is a bad time for selling your holdings it is best now that you hold it anyway and wait for the bull run, this is also the right time to invest but on a selective coin because not all of them are worth-it.
selling it will make you lose so much that you have to be patient to keep holding the coins that you have. investing is a good choice but you have to be careful to take action, to avoid things you don't want to happen. all coins are not necessarily good coins so you have to research more deeply. now a lot of coins go down so this is the right time to buy it and remain optimistic and believe that in the future there will be an increase.
