Oh, can I make a hypothesis?
But I warn you, this is only a hypothesis and purely an assumption, and only my personal one, it cannot be used as a forecast.
But looking at some facts and observing other companies, I assume that $ETH will lose its leading position in the next 3-4 years, instead of it there will be something else (I understand that a lot is based on it, but the passage of time is unchanged)
Now it remains to find or guess who will become his successor... maybe you have ideas about this?
