I am always amaze every time I imagine how much power does Ethereum blockchain has when processing transaction for every tokens it supported. There are millions of transactions are being process every single day. Just do the math. Decentralized exchanges using ETH blockchain plus online wallets like MEW, Jaxx, coinomi, Eidoo, etc. I always have this feeling that ETH will become number 1 someday. Who is better for you? ETH or BTC?
You are right about all the things you mention eth does but I don't think it will become number 1 coin any time soon, remember that there are many projects building the same smart contract platform? remember that most of the strong project on the ethereum network are building their own blockchain and when they complete it, they will swap an migrate to their own blockchain?
