If ETH continues to go up, we could see it going to 1000 $. I think it will be difficult because 1000 $ is a psychological barrier, but it would be great for the market to have ETH above 1000 $!. If ETH doesn't continues like this, we will se it going to the 863,78 $ support. I don't think that ETH would go lower than 863,78 $. ( Maybe if there's some really bad news )
