There are plenty of very good competitive that is now on-sight against Ethereum blockchain such as the polygon chain, solana network, binance smart chain and there is an announcement that even cardano will have its its own chain very soon.
Yeah, Binance smart chain is very popular because it is kind a 'copy of ethereum' blockchain with the smart contract.
Solana network is also my favorite blockchain, just look at the value of Solana in the market now, very high and already get #7 rank on CMC.
I hope ethereum network can reduce its gas fee to prevent ETH users leave and using other blockchain.
