Ethereum is getting popular day by day. People participating in ICOs they use ETH a lot. Ethereum is a smart contract.
But what does Ethereum do better that any other alt?
Probably the greatest advantage that ethereum has over most other coins is its popularity, this means that many icos are looking to release their project above the ethereum network because they know that a lot more people are holding ethereum than holding any other coin that belongs to another smart contract platform but if the popularity of ethereum subsides it is possible that it could be replaced by another coin.
