I prefer Ethereum because this crypto always has some inovation to give more advantages to the blockchain community. In the end of this year the price of ETH still able to going $$5000-$6000, because the fundamental of this coin very strong. the community, the team founder and the technology will be bigger in the future and give more benefits to the cryptocurrency community in the world.

Both are very good coins, maybe I prefer ethereum, because seeing the development of ethereum is pretty good now.

I think both are coins that have very good potential, but I prefer to invest in ethereum. I think ethereum is more stable than bitcoin and the price is much cheaper.

It's true, but I think bitcoin is still the best right now. being more stable does not mean better (IMO)

i choose both ....bitcoin now growing up to be bright and always stable in high price it same happen with ethereum
keep both is better and take profit in the future

I think Bitcoin and ethereum Both will rule Crypto Market in 2018! Because without bitcoin you can't imagine ethereum or others altcoin. If bitcoin will rise then ethereum and others altcoins will rise too. So, in my view, 2018 Will be a good year for Bitcoin and ethereum both.

When you concider the gained prices of both coins since last year's January you can see Ethereum's rising is pretty astonishing. It's ERC20 offers a lot for the people who tries every now and then to create new tokens. Though the network of Ethereum is still questionable and since the Bitcoin offers something unique like wider acceptance among the investors- it will still rule the market for a long time.

BTC is price can not be compare with ETH for one day, Btc is always be a winner any every where in the world and still be the number on the cmarket exchange, include on the coin market, is working perfectly to maintain the position, BTC still be the best for more 20years and nothing can stop Bitcoin not to be a leading coin.  

In this year, i think Bitcoin will remain king in the cryptocurrency world. And if you are going to compare it to ethereum, ETH has a long way to beat Bitcoin, though Ethereum has potential but it will comes after Bitcoin.
