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.
of course we have to keep buying when the value decreases. Of course, with every predicted increase in each coin that we will buy so as not to experience losses. Because not all coins will rise again when they decline.
