Do you believe Crypto will ever reach mass or global adoption?

Are we living in a dream ever believing Cryptocurrency will reach global adoption, and act as either a replacement or widely used alternative to standard currencies by most nations and companies throughout the world?

Or do you believe that actually this is something we'll see in the next few decades become a reality, and the uses proposed and improvements will bear fruits and Cryptocurrency will become adopted?

If I'm honest, I struggle to see it ever replacing fiat at least in its current form, I think nation backed digital currencies are very likely with CBDC's, but I don't think even they'd replace cash persee, due to the potential risk of control that would bring.
