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?
But now, seems like the peoples participating in ICO are reduced greatly, therefore the number of ICO's created are few too.
Investing in ICO is a good option, but unfortunately there were many fake and scam ICO's in the past days. But there are still some great ICO's to invest and worth, of course.
