The decision really boils down to the preference of the individual when it comes to his/her profit and investments. If one speculates that his/her investment would benefit in the future, then withdrawing it at an early stage is unlikely. But when the individual sees his/her investments only for the short-term perspective, then that would benefit them. Do remember that people generally invest into bitcoin hoping that they would yield profit in the long-run. But in the event that an opportunity like this one arises, then the obvious choice would be to cash out it.
