The whole freaking problem is that crypto turns out to suck absolute cock as a real method of paying for things (Said as someone who has actually paid for items with bitcoin, incl on the OG silk road...)
How many of these folks investing in bitcoin have EVER bought a physical item at a physical store with it? Hell, even online stores... how many of these people are actually using these things as currency, instead of as pure speculation plays?
The answer is a resounding "Almost no one".
They're a complete crap way to pay for anything that's not literally illegal to buy.

And there is no utility to the coins unless you're either buying things with them, or speculating that you can exchange them for more of a usable currency at a later time. Period.
