The "free market" as a whole will never accept 'all' the cryptocurrencies out there that have splintered into several hardly distinguishable variants, or even the top 3-5. No fkn way, too much confusion, too much integration, too much hassle. Not worth it for industry merchants to do that and support integrating them all.

If they are even going to do it at all, the world markets and merchants will only consolidate on the ONE cryptocurrency with the most end user popularity, the most industry backing, the largest ecosystem, the strongest brand^TM recognition.

Everything else will just be noise, and probably not even a close second.

We've been through this same competitive shit before.

It was called the enterprise search engine wars. Google won.
It was called the smartphone marketcap wars. Android won.
It was called the commercial desktop OS wars. Microsoft won.
It was called the enterprise backend server wars. Fedora/RHEL linux won.
It was called the social network wars. Facebook won.
It was called the privatized corporate Intranet wars. The free Internet won.
