Widespread crypto adoption - what could the threshold be beyond which there has been sufficient pubic exposure to crypto that it can be considered "mainstream"?

I was wondering this recently - you could buy pizza with bitcoin over 10 years ago, but it was more of a novelty than a "thing" - you've had the crypto ATMs, but again it's not really mainstream.

What kind of event or occurrence would make crypto an ordinary thing for people?

Is it even possible do you think? There's such volatility with crypto prices currently that surely it's going to struggle to be something that ordinary people would ever get paid in (sports stars etc. can afford to absorb the fluctuations of the market since they probably have a stack of conventional assets), and is it realistic to think that any given cryptocurrency will achieve price stability without itself being tied to an underlying fiat currency?
