Ethereum has a lot of coins at the moment that are trying to steal away its thunder and become the new home for all ICOs. Without ICOs ETH would be worth near nothing. If more advanced blockchains can be developed that offer faster and cheaper transactions then it's natural that people will slowly transition towards them. NEO at the moment is the main one but in time it could be blockchains such as EOS, Zilliqa or Credits.

Oh, so stick to bitcoin.
