Just sell it, it might fall even further.
First, I would like to let you know that this all depends on the market cap, when a coin is not getting or attracting investors then it wont be rising in price rate, it will remain low at price rate. So as for what I will do if Im trapped in a shit coin what I will do is to check online for a legit site or exchanger that buys the coin, if there is, then I will sell to them.
Next is to check if the exchangers running the shit coin allows withdrawal of money that was invested, if they do, then I withdraw. Lastly, this might be a bad one, but I will look for someone I would trick into buying it from me, lol.
