don't worry too much and in this situation it's better if you keep hold your coin but if you feel uncomfortable in this situation because day by day the market are getting worsen and you feel tired about that, of course you can sell it, no one will forbid you to sell because that is your decision.
To sell a coin in a falling market is not a way out of the situation. You will lose money and after the market starts to grow actively you will be very much sorry about having sold your coins. If you have savings that are enough for a living, then I advise you to keep the coin at least until the purchase price.
