Ethereum's genuine killer is BNB. look the number of individuals are discussing the binance smart chain recently, and investigate the presentation of the BNB coin in the market today. Polkadot can't be lined up with ethereum yet, so it is extremely unlikely DOT can murder ethereum. Polkadot is just utilized as an elective decision and has not had the option to contend with ethereum.
sorry it seems not, the number of people discussing BNB is not a factor in thinking that they are capable of being an ETH killer, because in fact the increase in BNB is also influenced by high ETH transaction costs, so investors are looking for alternatives in investing. the alternative is BNB because it is in 3rd place in crypto. Of course investors do this while waiting for ETH to find a solution to this problem.
