I am expecting sonm to go moon next more than anything. They are developing it slowly but it is coming. It has neat structure and I think it will really help many people to complicated calculations.. Wait and see.
It is too early to say anything like that because there are not so many people around the world who are aware of the sonm. Even if this is the coin which will rise higher to the moon, we need to wait for some long period of time as this coin is still in its development phase and that it will take years to see it growing and making some better reputation in the market. For now, ETH has brighter chances.
