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?
We can't say that certainly.
It is more dependent upon the network congestion. Many people would have replied that ETH is faster, that might be a case as for now. But if ETH starts hosting the transaction traffic as comparable to that of BItcoin, we will discuss the matter then. Recently, there was a ETH congestion due to some exchange. Th transaction fees were pretty high during that time and speed was quite slow. BTC transfers were pretty better than ETH then.
