Now ETH price around 500$.Will ETH price reach 1000$ in 2018 Jan

I believe that etherium has a bright future, etherium might go the same track bitcoin have gone through. Though it is now going with bitcoin's move, definitely it will have its own path. Knowing that it is niw considered coin second to the bitcoin. Im pretty sure that more people will pay interest on it. In addition, it is actually a good investment knoeing its demand is also increasing and getting mote popular in the market.
I agree with you, ethereum has a lot of potential to exploit, it is in daily development, they always make progress, I look forward to the change to proof of stake, also known as the "casper" phase
