When the price of bitcoin was $17000, many people said that the price would not fall, then the price fell and I remember that at that time I panicked and sold at $16000 and did something very good because the price fell a lot , the price dropped to $3100... sometimes panic and sell can be very beneficial, it can save you from a big loss. Of course later I learned to control my panic and today I do not panic. But it was a good decision to have sold us $16,000
If you sold at 16,000$ resulting from panic selling, then you decision is a good one. Now you can see the price is near 4000$. If you have hold at that time, you would certainly have regretted. However there are only these few cases where panic selling gives you profit. In most of times, panic selling result in only confirmed loss.
