I agree. The failure of Ethereum to continue growing and expanding, despite the passion of it's community demonstartes that it's difficult to onboard the world to one chain.
The success of Binance Smart Chain, Polygon, Tron, Solana and others demonstrates to my eyes that there is plenty of customers to go around in this space.
I think Binances CZ said that he encourages his competition and focuses on making his product better, because the current customer base is so small compared to the rest of the world, that we shouldn't fight we should cooperate.
