@jeline...First, Bitcoin could still keep the leading position. But just because people still beleave in this. Because Bitcoin was the first. There is no other reason. That's too risky for me. Steemit everybody can see here. It works. It's the only application it is used on this scale. I'm convinced about this application but not 100% about the security of the blockchain-principle (graphene) behind. I follow this regularly to get more infos about that. Ether has also applications they are in use every day. For example ICO. And also AXA (big insurance company) is selling flight insurances over Ethereum and many others. But each one of this applications are not so big like Steemit. Steemit couldn't work with Ether because it would be much too expensive. But the security is 100% sure with Ether-Blockchain. I comprehend the principle behind. Very secure. I could go even more in detail. There are no other Coins they have applications in the real world. So I focus on Steem and Ether. Maybe one day I see that the Blockchain-principle of Steemit (graphene) is as secury as Ether. Then I would change everything to Steemit or Bitshares or EOS very fast.
