Both of the coin seem promising in the future, however i think eth is more popular than risk and more people are into eth than lisk and there is been a great rumour eth is going to rise high
Yeah ETH is really popular even when I ask co-bitcoin users they all say ETH is really looking great. But it is price is too high so if you are at minimal risk or just a starter LSK could provide some of that.
If the Ethereum is very useful in the real world usage, the price is not too high. If there is no use, the price is 0.
