In my opinion, there is nothing like eth-killer. BSC, Dot, Solana, etc are rising for the trend this time. But they can't be Eth killer. Possibly, they will sustain beside Eth. Maybe you heard today, Solana was down. So, nothing can be compared to Eth
Or will Eth 2.0 kill all above in the list? But then again Eth 2.0 is like Coca Cola Brand in the Crypto market so there's always a Pepsi like Brand competitor to Eth 2.0 right and if so which Blockchain do you think it will be?
Eth 2 may kill them.
Which blockchain is the Fastest, Cheapest, Most Secure Cool? Usually this determines the winner right?
I guess it's Solana. It's fast, cheap. But for security, Ethereum must be the winner.
