Ethereum is going to take a big leap when they get all of their updates sorted out. I think ETh is going to be a bigger gain then BTC.
Buying ICO via bitcoin and $ start switching to ethereum payments, this is a sign that they will be very popular to use because many projects choose to switch to eth-based markets such as etherdelta, volume levels that prove eth has a bright future. I'm not saying they will outperform bitcoin but you have to start conversion gradually from now on.
