In my opinion,it really depends to your goals,But for me,I want to make a profit everyday than holding a bitcoin for a long time.Before ,I was thinking to hold my bitcoin whatever it takes but I realized its not healthy to be affected when bitcoin is fall everytime you check it on the market.So set your goal and learn when to enter and exit in bitcoin .
I'm prefer to hold Bitcoin for Long time because it is like saving for the future. Even the market value of Bitcoin now is very low but it can't affect my faith that Bitcoin will going to peak soon.
