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?
If we compare, let's just say using the same fee, and there is no network problem between the two, then most likely, Ethereum will win. Because I think that making it quite slow on BTC transactions is 1 txid has several sub transactions (CMIIW) while its not happen on Ethereum
