$ETH

Is ETH stronger than the largest digital currency? If not, developers will start to develop on the first blockchain, the one that attracts the most funds. Or towards the cheaper one (the most economically viable).

Then it will be the end for it.

On the other hand, if it is stronger, then everything is allowed for its future. It will be the place to be in the coming years, attracting all developers and becoming number one, and its valuation will make a good upward move, significantly increasing its value.
