Nobody wants to be monitoring the prices all day with the cursor on the sell button just waiting to click the mouse, so how do you decide when to sell?
If you set up an open order with a low target price, you'll be disappointed when the price climbs well above your target price.
If you set up an open order with too high a price, you might not sell at all.
What's your strategy?
I sell the bitcoin I have when the price reaches the target I want, I will not regret it if the price is better than my target, because I know that this is a risk that I will face.
Then I will wait for the bitcoin price to go down to buy it again, and will set up another target price when I sell.
