Ethereum has a great potential of growing and we can also see that a lot of new projects are being traded in pair only with ETH and not with btc. But bitcoin, don`t stay on one place and they are also improving themselves. We can not tell exactly how things are going to be, but it hink in future both of this currency have the potential of growing.
Correct Ethereum is stronger than bitcoin and it has a great potential. But the biggest problem is smart contracts and unfortunately ETh cannot handle such ammount of projects, thats why we have heard some negtive news about hack attacks and etc. I think if other projects that offer smart contracts will finnaly release their systems, ETH will feel its self a little bit more comfortable and than we will see a good growth.
