I am currently finding out more about altcoins. Let's say there is an altcoin with a market capitalization of USD 250 million.

A fork of this altcoin is created that is better, actually offers a general usecase for many people and on which a new ecosystem is built.

Is there a psychological price border that the altcoin fork can never surpass the market capitalization of the original altcoin? No matter how much more useful, adapted, better the fork is?
