if I become you I will sell what has value and change it in the form of other more established altcoins, and if there are a number of potential altcoins in the future, just leave it in the wallet until the price is worth selling, but I think that requires enough patience.
unequivocally it is best to sell those coins in which there is no trust, since this is the best way out of this situation, so that the proceeds can be invested in more relaxed and profitable cryptocurrencies.
