ADA has a big chance to topple Ethereum's market cap. What ADA can implement in their mainnet in September is Smart Contract, defi integration, nft compatibility… Everything looks very promising to make a big change. The nature of the altcoin market is always changing whether it is slow or fast to match. ADA still has the ability to do that although the gap is still huge.
Do you see both marketcap and volume at this point? because what I see between the marketcap and volume of Cardano with Ethereum is still very far even almost half of Ethereum, so to overturn Ethereum's market cap, it still takes a long time for Cardano to do so.
