If you have a lot of resources and have enough money to compensate your needs.. then selling your Bitcoins is not an really option. You should invest with your Bitcoins rather than selling. Just my thoughts. 
but I think even if you still have the big money in real life and you do not need the money anymore, does not mean you do not sell your bitcoin that moment dude ? I think it would depend on the circumstances of the current price? of course, if the current price is high you should sell it and take advantage of that opportunity, because the opportunity will not come twice
