As of today there is no doubt that Ethereum and its ERC-20 compatible token has been widely used by ICOs and other platform for some crypto-project but for the development of cross-chain and multi-currency platform thereare a lot of projects that taking advantage of this Ethereum's weakness - the un-connected block chain, think of it the KOMODO project as an example for cross-chain blockchain interconectivity, it can be undervalued as of the moment but in the future it could be widely used for dICO (decentralyzed ICO) - UTRUM project is an example.
