Bitcoin, I believe, will remain the dominate crypto currency, but will not maintain it's first place rank based on market cap. I believe the ETH will overtake BTC in the not too distant future - "The flippening".

I'm extremely excited about the off chain developments (LN) that will increase BTC's mainstream adoption. It's simple, if there are issues or design constraints we must identify it and fix it.
