ethereum biggest contender is binance coin.. bnb has a big potential as well as those in the top 10 list.. but the thing about this ethereum even though there are a lot of coins out there it seems that eth is so popular..
Yes I do consider binance over other coins because binance coin also having use case as it use as a internal currency got the biggest exchange in crypto space it’s used for trading fees . Also it’s having its own blockchain or smart chain which provided to create multiple blockchsin based project . But we can’t simply ignore Cardano it may be the future of smart contract if ethereum 2.0 fails .
