quoted from the article providedHe maybe is not talking about the near future as if we see the current situation now you will see that a lot of the new people will know the word Bitcoin first rather than the word cryptocurrencies, I do believe that bitcoin will be replace in the future but it won't be near as a lot of people are still are tapping the shallow parts of the world of cryptocurrencies, if the majority of the world has a firm grasp on this industry I think they will voluntarily pick the best cryptocurrency fit to become a global crypto, and I guess it must also have a major support from some developed countries.
