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

Well, I would say that since everything and anything has a possibility of happening in this market, then I could somehow say that Ethereum reaching 1,000 dollars could have a chance. However, on the one hand, I would also say that if you follow the path Ethereum has taken over the past several years and months leading to today, I think that that high of a gain, which is 100%, would be a bit far for Ethereum to reach. I say that because of the fact that Eth usually gains slowly and its manner of gaining value is comparable to crawling. It's character is more on the reliability and enduring nature rather being quick gaining like Bitcoin.
