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?
For me ethereum is useful since you can only use one wallet for your erc-20 token . Ethereum also has lower fees most of the time that's why people love to use ethereum . The mere fact that sometimes ethereum is congested is because more people is using it .
