I think in the form in which crypto exists now she can't live long, most likely it will change,transformed, but still remains
Good day!
There will be competition between currencies, and it is difficult to say which solutions will win - some of the existing ones or radically new ones. In 2017, many considered Bitcoin an obsolete currency, and now it is again occupying more than half of the cryptographic market. In essence, competition does not occur between current technologies, but between development teams that are willing to improve them.
