if you bought something and there was a real chance it could be significantly cheaper or significantly more expensive tomorrow, but also that if you wait long enough the general trend would be becoming relatively cheaper as your money gained value, would you be inclined to spend it then or hold onto it? even before considering any technical hurdles crypto has become an intermediary store of value rather than a true digital currency and even from the outset when it was being used directly in exchanges to facilitate largely illicit transactions it was still just an intermediary then too. while investors might want to snatch it up generally speaking a regular on the street level sort of business isn't going to want a currency thats both not widely accepted and that's tanking in value becuase they have immediate expenses to pay so it's bad for transactions there if the market is crashing and simultaneously no one wants to let go of it when it's growing in value so it's bad for day to day transactions then too. it wasn't the intent but an investment vehicle and a hedge aginst inflation is what the wider world seems to have turned crypto into.
