So far ethereum is still the queen of the Dapps.
Let's hope that what many new blockchains say about scalability is true and have other options. But above all to push also ethereum to improve the scalability aspects.
Competition is good for the market, for the users.
'Ethereum is reached to 1000TPS easily on testnet.' Vitalik said.
Any project and claimed they can or already solved the scalability ,reached 1Million TPS,or anything before mainnet alive.This is mainly just for market promotion,do need to take seriously.
So,just release the fully decentralized mainnet and let community check the result.
