No one can give the correct answer because the have different strategy and mindset. Most people will say 6 month - 1 year but that is relative, so I believe you must find your sell area ( take profit ) it self. Besides that, good profit also has number and some people really need only 50% not 100%. People say need only 50% because that's strategy to grow up fund not take profit direct into wallet. Up to you and see you next time.
