Imagine what will happen if the eurozone crumbles.
Right now Germany, France and Italy are trying to keep the ship afloat, England is starting to show the middle finger and the rest is just watching the chaos unfold. It can't go on forever.
I don't think we'll see any crumbling anytime soon, you'll see how the news stop talking about Greece for a while and we'll (by we I mean the average clueless joes) forget about Greece and what happened, just like "we" forgot about what happened with Ebola (notice how it was all over the place and not Ebola "doesnt exist anymore". They'll use this sort of tactic, and once shit hits the fan for real it will catch everyone by surprise and the smart ones holding BTC will visit a place called moon.
