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.
There might be reason why he would do that. Maybe he had sold his coins too early and he heard news that it would surge more so the only thing left to do is buy back as he had the gut that it would pump soon again, it happen to me too.
