Without any doubts they are both really good choice, but I would prefer ETH, because of it's opportunities.

On my opinion , I think ethereum is better than bitcoin, because etherum is simplest and Ethereum is an open software platform based on blockchain technology that enables developers to build and deploy decentralized applications so i choose ETH. but Bitcoin is bitcoin it is the mother of all alt

For me bitcoin price is much more higher than ethereum so i would rather say that i will choose bitcoin but in terms of a promising coin that will be successful in the near future then i would go with ethereum. These coins both have the same potential and same benefit that we can get. Both coins can give us profit but if we look at the market the ethereum will be tha coin that will increase its price significantly while in bitcoin it will still be volatile and more likely to decrease for the mean time.

i choose both, Bitcoin (BTC) and Etherium (ETH).

but BTC is absolutly stronger and the number one coin of cryprocurrency and the seccond coin is ETH.
now my asset in crypto is half for BTC and half for ETH.

i hope so BTC is back in $2000 again.

In terms of increases in percentages, I think ETH will come out on top, because it is more promising. Since bitcoin was in the forefront, people got to experience problems related to bitcoin more, whereas ETH flew under the radar, so to speak. So ETH will have more room to grow within this year, hopefully.

The year 2018 began to be troubled. I do not think we need so many coins. balances and graphics in the crypto money market are constantly changing. The btc variable is more stable than eth. prices will increase towards the end of March.

ETH will conquer the crypto world ruled by BTC. A lot of exchanges pairs ETH with most coins for trade.

I think bitcoin will still win this year. There are a lot of services offered by bitcoins compared to ETH. I can even pay my bills or book a plane ticket using BTC while I can't do anything on my eth unless I convert it to BTC. I don't know if its the same thing in your country but services really matters if ETH wants to beat BTC. Alts are also relying on BTC, without btc our alts will just be nothing.
