You don't only buy Bitcoin to make a few dollar profits, instead you accumulate as much as possible and hodl, for it is the amount of Bitcoin you have and how long your were able to hold that will determine how much of profits you will have, buy and hold Bitcoin for as long as achieving a reasonable size of Bitcoin possibly within 4 to 10 years or more that you can have a compounded value of your Bitcoin investment over time, yeah you can do whatever you like, but just Note that Bitcoin is best performanced when view on a long term perspective.
