Yeah, i would never touch my stack.
BUT, if it suddenly became commonplace to spend bitcoin, I might from time to time buy a little to specifically spend in a specific store, to sort of support the movement.
When there is a legit reason to spend your coin, it is not out of place to do so even if you are not doing it just for the purpose of supporting the increasing need to advocate for the usage of bitcoin for the sake of making payment.
Factors like the stability of bitcoin price is going to be one strong determinant that will tell if people will be ready to spend there bitcoin, take that out and it will become really difficult for people to spend there bitcoin for making purchases in a time when the discussion is more about the price of bitcoin going higher and placing more people in great profit. the plan of many will tilt towards how to build a more robust stack rather than selling it out.
