why do people panic and sell their coins throw some light on this topic and share your opinion
Not everyone who sells their bitcoin, or any other coin per say, while the price is going down is panic selling, some are actually consciously selling in other to buy back when the price has significantly fallen, this will enable such individual own more coins than he or she initially owned.
I particularly do this at times with some of my altcoin holdings, and to me this is another type of trading, it makes no sense to hold a coin while you are watching the price going down, that is always an opportunity to own more of that coin if is truly one with lots of potentials, so, what I do is just sell it, and wait for the price to drop further, then I buy it back with all the funds, by doing this, if I had only like 1000 of that coin before, I may now have like 1200 or even more, depending on the price level I sold, and the price level I bought it back.
This is another trading and accumulation strategy, though not one without risk, for there are times the coin price will start going up just after you have sold and waiting to buy it back cheaper, you end up buying back at a higher price, losing some potion in the number of coins you previously held.
