I wouldn't want to compare BTC to ETH because both have unique features. The thing is, BTC has gained and cover more grounds than ETH which is why it's accepted widespread and has more value of course. ETH which we all know to possess indispensable features like its blockchain, its decentralized exchange. Those features of ETH are integral parts of most alts so given this, ETH anchors so many coins therefore without a doubt ETH is just getting started, we'd see the moon behind it soonest. BTC equally has potentials still, after the fork issue and all other controversies are settled things would come back to normalcy.
