I know it's advisable to buy low and sell your coin at a higher price. What I don't understand is that when you sell high, do you suppose to buy so that your profit will not depreciate when the price is going low? I need an expert to clarify me, Thanks.
We have different ways on what to do with the profits we jave gained in trading. From my personal experience, my profits will be use to buy another altcoins at the dip. Or I will add some bitcoin to my wallet from the profits I got from trading. Not everytime I do that, I still spend some of it by buying some few things I need for my personal needs.
