sell it today or recent next few days should not considered as smart move;
AD it or not, that depend on your tolerance of risk;
but buying either other stocks in the same pack (industry) good or even just buy something else not in the same industry to reduce the further risk would be my choice; why keep gamble on something short term may go worse; there is always a limit on one stock that you should hold and bet;
and, please remember that you never be able to earn the lost money back from the stock market; but you always can earn extra money from what you do on the next right move; they are tons of other chances there ;
good luck; and don't blame yourself, DPTR has very high probably back to your price if it not above 5$ ; just be patient;
