This will happen soon. As time passes, mass adoption of cryptocurrency is increasing with business communities accepting cryptocurrency as a method of payments and some countries issuing their own digital currency. Even China, which came down heavily on cryptocurrency, is now becoming flexible and is reported to be issuing its own digital currency. So I am very optimistic about it.
I think if cryptocurrency price is still up and down drastically and still played by whales, i'm sure crypto won't adapted as a mass adoption because people could manipulate the price and could buy anything that they want with lower price and it cannot be implemented in a realworld
