Maybe Polkadot, but there is someone who says DOT is HYPE and the pump is too big. But I believe Polkadot can replace Ethereum's position, especially if it fails in 2.0 later. So far "Ethereum The king alt", it's really hard to beat, but there is still some hope for a potential Top coin. and if ETH 2.0 is a success, there is no hope for the other coins to beat.
