I know many investors who are suffering from holding old altcoins that have been laying down in the dumps like anything. The best way to get out of them is to sell at whatever value possible and then forget about them. You might be at a loss, but it is better to move on and accept the loss than keep holding them.
Not sure about old altcoins but i am still holding tokens which were hyped during the ICO boom and during the last rally it gave many opportunity to book the profit but after the correction mostly all of the coins went down drastically and some of the coins are worth a satoshi right now and showing no signs of any movement, already accepted the loss but the volatility is also less to sell everything.
