If BSC wants to beat Ethereum, they need to be more de-centralized. As long as BSC is centralized network, it is of no threat to the ethereum. People prefer decentralized network over the centralized ones and that's the major reason both bitcoin and ethereum consists of 70% of the total market-cap.
That's right, that's why I have also told several people in this forum that the Ethereum mainnet and the BSC mainnet run on different paths so that the two of them will not threaten each other because with this BSC it can add new network options in the crypto space.
