Panic time means BUY TIME to me. Every time that people says is panic time, BTC's price is almost on the floor. So, I can buy it at low price and wait until it recovers.
Well said if the Bitcoin price is falling means it is a BUY time, not panic time. If you get panic and sell your coins, it is a loss for you but it is an advantage for others. They will get bitcoins for a low price. So whenever the price is falling just hold your coins and if you can try to buy some more coins. We will get very less opportunity to buy bitcoins at a low price.
I understand that falling price makes us quite worried about our investment but investing or trading is to overcome those kinds of fear. In bitcoin, we have that guarantee that its value will continuously go well because of the rising demand for this. Therefore, in times that its price goes fall, then we shouldn't be in panic instead take this as an opportunity to but more coins for future earning.
