That is an interesting point.

As I was reading through the literature survey, I started thinking about how valuable bitcoin will be for international tourism. I'm sure plenty has been written about that already, but I had mostly thought about cross-border payments like trade or remittances. Being able to bypass currency exchanges by just spending bitcoin when you're travelling is going to be huge, eventually.

The thing that made me realize bitcoin will never go to zero was just seeing that there will always be at least some fringe weirdos who keep using it and mining it.
