Of course, the coin Ethereum is very promising and the leader among the altcoins. But overtake bitcoin is for the Ethereum now is not a real task. I think in the future bitcoin will remain the leader.
Right, in my opinion among altcoins, Ethereum is the best coin, because it has good potential.
but Bitcoin is a coin that is first known by many people and has good potential too. so Ethereum and Bitcoin are crypto's future.
ethereum to compete with Bitcoin is difficult and of course the most superior bitcoin.
