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?
There is no doubt that in case of eth transaction , transaction time and cost are much much lesser than btc transaction. But as I think only transaction time and cost does not create coins value. You have to always keep in mind that Bitcoin is the first cryptocurrency and creator of all. I had also a feeling that in far future maybe someday eth can be stronger than btc. But that is not in near future ( not in 1 or 2 decade).
