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.
buying low and selling high is the thing to do. but I see if we make purchases and sales at high prices maybe we should also wait for prices to go back down to buy back, because if we buy at high prices it is a speculation and if prices can be high it can be our profit but if prices are at low position, it might be a loss for us.
