Panic selling is probably the worst thing a trader could ever do with BTC. That happens because people invest and buy more then what they can afford to lose because If they didn't buy more , they simply wouldn't care , have patience and wait whatever time It takes until It raises again.
People who bought more then what they can afford to lose are always in panic and the least drop in the price could make them panic sell and that could result into losses , however If they waited , It could've go up again.
Agree with this one
Panic selling when the price of coin goes down. but that's a bad habit. as a professional trader you must always wait for the right time to sell or buy also its come with great responsibility in news/update of what you are trading also my friend sometime or maybe always too much is bad. Trading is basically on your hand how you will work for it, only enemy here is the time when you can wait you will never lose.
The panic selling no doubt is a bad habit but you also have to look for your money that you have invested. I have learned that a dollar today is better than a dollar tomorrow, at that time I didnt understand its meaning well but for now I do know it. Guess what when you realize that your investment is drowning so then it is better to pull as much as you can from it otherwise you will have to bear the consequences not in your favor.
You need a change strategy for your trading each time; this is how you will be successful in trading.
