It is because of the reason that I know this thing that there is nothing more profitable than that of holding. I only sell at the time of need.
I don't think that people will never sell their coins as and even if you will never sell then how you gonna become billionaire and even at that time you will think of holding it to sell when you become multi billionaire and holding it too long is very risky as no one knows what will be the scenario in future so its always good to sell it at higher profits and buy it back at the dip.
Those people who are holding bitcoin with blank minds often don’t sell off bitcoin when the prices are damn high. In the way they miss the chance of enjoying huge profits with bitcoin. Setting a goal is essential for achieving it.
