Since Ethereum managed to improve on Bitcoin and replace it in some ways, it is expected that the same will soon happen to ETH as well. So far, the most likely candidates to do this are NEO and EOS.
Both coins have seen a lot of success recently, and EOS even managed to launch its MainNet, only days ago. Still, if Ethereum doesn’t start improving, and soon, it will be replaced. The only thing left to be determined is which of these coins will be the first to do it?
