Dont think it will happen because of its mass scale adoption acros the world and pretty much everyone heard about it.Yes bitcoin have problems with transaction fees and time of it but eth isnt really much better,thing that people are forgeting that btc isnt over with improvment for example lighting network should be up this year for btc
Actually it is bit early to make comment about this debate. We should see how they will survive after this panic selling. if btc stays around where it is and eth goes over 1200 usd, then there is sign that good boy ether can outrun btc.
