If so, when?
I think that Ethereum has prospects to cost more than one thousand dollars. In my opinion, 1000$ it will cost by the end of autumn 2019. You must have patience and not worry that now its price is 100$.
There is a great probability that ETH will gain a lot after its fork. The Ethereum team said that it can happen close to January 14-19th, 2019. probably, after this event, the altcoin price will grow but it can reach $1000 later.
