I stii think that ethereum is not better than Bitcoin, though it can be the king of smart contract and current maintains the number two most popular coin. Obviously it is very difficult for altcoins to overtake bitcoin in all levels, like popularity, adoption, awareness, most used coin in the world etc. Eth ihas actually brought huge development into the crypto space but is not the most popular or the best project for now. I hope that ETH will become the number one coin/token in the future
