Polkadot is categorized as a coin that has good prospects for short-term and long-term investment, but polka-dot cannot kill ethereum because the Ethereum network is still far superior to polka-dot so ETH will continue to rank second after bitcoin.
Well, for now, the potential for polkadot to beat ethereum is very small. even a coin as big as BNB is still having a hard time catching up to Ethereum for now. well, however, the polkadot target before reaching ETH is BNB. however, it seems that the potential is also very small for that. yeah, but I'm looking forward to its development in the future.
