Panic selling will just make your investment fall into losses so if we can still handle the pressure, then stay calm and be patient for the sake of future profits. Although panic selling sometimes becomes inevitable but the more we do it, the more chances we will lose all what we have started.
Even myself still fall into panic selling sometimes especially if some emergency cases suddenly arise but as much as i can do, i will never push through it and still think panic selling should not be our last resort. We can lend money to some friends if badly needed but selling our hard earned coins is not really worth doing.
Panic selling takes place when heavy pressures show up inside the market, when price falls hard if you don't have the nerve to take the risk, then expect that panic selling will happen to you.
It's always good to calm and never to rush your decision. Evaluate the situation and make sure that you judge things according to your knowledge.
People learned from past mistakes you need to work with deeper knowledge, so in times of critical situation you can judge it up to your best understanding and avoid losing or lessen the chance of losing your money.
