Give me ONE example.
OK... just for the sake of argument... Litecoin.
For all essential aspects, Litecoin is a virtual clone of Bitcoin. The only thing differentiating Bitcoin from Litecoin, as viewed as the "other alternative" is the relative 100:1 ratio of market cap.
Granted, that is a significant difference from the aspect of the "other alternative". However, even Bitcoin is still a sideshow on the world stage. What if adoption in the coming years is driven to Litecoin rather than Bitcoin? Then Litecoin would end up the economic juggernaut, and Bitcoin would be relegated to junior status.
What might lead to mass adoption of Litecoin over Bitcoin? If Litecoin were to have increased utility to its user base, that is something that might lead to this eventuality. If something increases in value, it is a more compelling investment to the individual that some other thing which does not. And individuals are the decision-makers who allocate their resources to products and services.
What might lead Litecoin to have increased value with respect to Bitcoin to each individual stakeholder? I might posit that Litecoin adopting higher tps capability while Bitcoin does not might be such an eventuality.
So if such were to come about, and Bitcoin's market dominance be shunted to the side by Litecoin, why would Bitcoin's properties matter in terms of being the "other alternative"?
