In my side ill choose bitcoin because etherium is getting started while the bitcoin is so popular so many people will choose this but maye there might have a tie.they both easy to invest and very secure

I'm going with Bitcoin

On your position, I'd take Ethereum
Because, firstly, Ethereum has up-down trends from day to day - a perfect time to make some profit from trading
And secondly, In future it's gonna go up "to the moon"
But, this is just my opinion
I've already bought some ethereum
And hope for long hold

The answer to your question depends on Vitalik's decision whether he will do the fork or not. If so, the risks will be greater for Ether

I think Bitcoin is always better then Ethereum. I have invested in both and will keep my investments, but Bitcoin is the leader of crypto and there are no signs of changing.

Of course bitcoin is the king, they won't be replaced by any other coins because bitcoin are more popular than any other coins. So it will keep in the top rank of cryptocurrency.

Do not oppose bitcoin and Ethereum as they have different functions and different goals. If bitcoin is an alternative means of payment, Ethereum is a platform for smart contracts. And in portfolio you need to have both of these coins.

It depends on your investment objectives and risk tolerance. If you want to just buy and save one cryptourrency, it should be Ethereum. I must warn you rather than holding Ethereum not for the faint of heart. If you're the type that panics sells when you see your investment down 20-50% then it's not for you. If you will quickly take advantage, then it may also not be for you. If you want to invest in the long term and last for at least a few years, Ethereum can be one of the best investments you'll ever make. If you prefer risk, you can use Bitcoin or a combination of Bitcoin and Ethereum. Bitcoin is significantly less volatile but has less upside potential.

I don't agree Bitcoin is a means of payment. Even lightning network doesn't make it so. I believe that the main property of Bitcoin - reliability. So, Bitcoin is a store of value in my opinion. But i agree that BTC and ETH are different and shouldn't be compared. Both of them have big future.

I also still choose Ethereum. my great hope for Ethereum is, may Ethereum continue to sustain its growth and continue to grow. especially in the year, 2018 Ethereum continues to show a pretty good development.
