You have to realize a decent amount of the people that have started investing since 2015 no longer think of Bitcoin as the next big global currency, or at least they don't privately think that. Most of the time they're interested in hyping their investments so they can get more money to benefit themselves, not for anyone else. That's why you see some people opting to take their money and exchange it for goods before it reaches that status; because they think it never will.

I'm personally on the fence and can't tell you if it will or won't become the next big thing. I am hoping it does, but I fear if such an event occurs it would destroy the community we've cultivated and there would no longer be the enthusiasm, albeit sometimes out of place, that comes with it.
