The top ecosystems are a couple of years old, including Ethereum, Solana, Base, Avalanche etc. But even tho Bitcoin was the first cryptocurrency, it's underlying ecosystem is very new, this includes Ordinals and Runes. There's still a lot of growth and if history shows something is that the early adopters become the biggest winners.
