The market of crypto currencies is so unpredictable that you can expect any incredible things. In my opinion, in 2018 the ethereum will grow faster than bitcoin. But the probability that ethereum overtake bitcoin is small enough. 
I agree.. I believe ETH would be higher in price in the future.. maybe $3-4k in the end of this year,, and ofcourse we can hope for more than $10k like BTC...
But I think when that time comes, BTC price will be higher too..
BTC is the mother of all crypto,, and I think BTC price will be the highest among all coins ~
I agree that BTC is the first and always be the number one coin..
When ETH rise, BTC rise also.. I think there will be no day when ETH price is the same with BTC price.
can be, within five years it seems the bitcoin would begin, whether it's replaceable by other altcoin or ethereum. This happens because many investors are also moving both switches to altcoin from in the bitcoin.
Nobody can make sure of what will happened 5 years from now.. But I think it is more likely that people switched from BTC to ETH won't be happening~
