There could be a chance that investing in stocks/bonds is like burning your money in x years time.

"Aye, we talked about it. Have you ever been in a city under siege? Maybe this part's not in your books. See, it's not the fighting that kills most people; it's the starving. Food's worth more than gold. Noble ladies sell their diamonds for a sack of potatoes. Things get bad enough, the poor start eating each other. The thieves, they love a siege. Soon as the gates are sealed, they steal all the food. By the time it's all over, they're the richest men in town."
-Bronn, Game of Thrones.
I mean that in an economic crisis, you will trade all your precious bitcoins for a potato.
