I guess that is up to you, and you can sell right now or still waiting for the price moving to the higher price. It's not about when we need to sell bitcoin, but it's about how much profit you want to make, and if you do not see your profit, then you should not sell and only waiting for the price. Maybe bitcoin price will increase in the next few hours, tomorrow, tomorrow after or in the next month or even in the next month but the truth, only we can decide this.
