Different investors will have different strategies. Many investors are feeling stressful with the low price and they got their loss. However, some other investors and day-trading precisely love this situation. The low prices indicate that they must add the amount by purchasing the coins at that low price and hopefully sell them when the price is higher some percentage. that is also what I do. I don't want to take soo deep think about the low price, just add my investment amount for some coins when it is low.
