The panic sellers face the loss. I won't suggest anyone to sell his coin if he bought it at higher rate and now the price is lower than that time. Agree with OP, just hold your coin until it goes up again. I have invested also while the price was up. And I'm waiting for the good future. I believe it will be up again.
only stupid fool will sell His coins at losses,though there are chances that in desperation that needed a money they tend to sell even how high they bought the currency.
Remember the magic word in crypto trading that "Buy Low,Sell high" and not buy high sell low .
so never sell unless you are desperately needed the cash.
