No one really knows when, 4 months after you post this, and the market is still just go up and downs, not bullish. It will likely go sideways until at least the halving of bitcoins. Except the altcoins can fully independent not affected by bitcoin price, but that things is also unlikely in near future. So, I think everyone should just expect a sideway market for the meaning time. And for the question about eth and btc? I don't think ethereum can catch bitcoin in near future, or even it will never, bitcoin is too strong.
