For now , i think it is the best situation for crypto market is to le the bitcoine be the dominant , because the team behind it have alot of experience , so the can handle every problem the crypto market face
I don't think Bitcoin will be dominant for a long time from now. It has had it's time, it's only natural for it to leave the stage and let others shine. 2019 will be year of lots of coins shining IMO, I won't be surprised if XRP or even ETH supplants BTC. Or maybe MFX - even though they may be fairly new. 2019 is definitely a year to watch out for in the cryptospace.
