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.
mostly I am not manage my prophets because I had some amount of expenses in my life so after the expenses I will save my I can come in the Bitcoin so that I will trade it for getting good profit.
