Your comment seems very confusing. An investor's goal should be to keep buying until they have accumulate enough Bitcoin in their portfolio and hold on to their holdings until their term expires. It depends on the investor whether they can hold on to their holdings. If a person is patient, they will be able to hold on to their investment. If a person is not patient, they will not be able to hold on to their investment.
You have introduced certain sentences into this discussion that ended up sounding confusing thereby comfllicating the investment process. To be specific, what do you mean by "until their terms expired" ? Do you mean an investor have a time frame to hold after which he can sell? When they sell off their Bitcoin after the supposed expiration, what next? Well, I don't share in this mindset because my objective of investing in Bitcoin is different; I plan to always have Bitcoin for as long as I live and when my time on earth is done, those coins automatically becomes that of my heirs as I will make the process possible even when I'm still alive and active since no one can predict what will happene even as we wish for the best of life.
I just hope that you are not being limiting yourself to thinking that the term for holding Bitcoin is only 5 to 10 years that was suggested in this discussion. Such range was only chosen as the least amount of time an investor is expected to see significant growth in his Bitcoin portfolio and not the time to sell. Please take not of this and make no mistake about it because Bitcoin is just getting started and it will not be wise to sell your precious coins when you should be buying more.
