yes you are right, ethereum is more accurately said to be the king of ICO. there are many ico projects that use the blockchain ethereum. but ethereum can also be said to be the mother of Shit coin on the market today. there are many shit coins that have no value on the market, the average coin is the result of a scam project or a failure.
