this move is appears huge in the crypto world!! but personally I don’t think it is a new bad news related for ETH, BNB, Solana and others.. because people mostly use those chains for stablecoin transfers!! but they still have big ecosystems with DeFi, NFTs and many more.. I think circle & Tether just want to control the rails and fees on their own dedicated networks. but the main question is whether users and exchanges will actually adopt this new blockchains because at the end of the day people will just go where it is easiest and there is more liquid but right now it is still Ethereum, Tron and BNB, so for now i don't think the news is bad for any of them.
