Yeah, surely we already know that there have been ICOs that pay hunters with ethereum and xrp coins. But that happens if ico project developers care deeply about the quality that determines the future fate of their coins in the future, because they are serious about creating their coins. The coin will have the direction to suit the purpose of the whitepaper of the project.
But unfortunately, there are few projects that make it to the top for various reasons. So eventually the project became undirected and died in the end.
