No one knows but talking about 1000 on ETH price is really hard to tell unless if the market movement or hype was just the same on that end 2017 hype.
If not then theres no other way to go into that level so easily.It takes time and it all matters with the demand. Just be grateful that we did able to pass
$300 at least and so as with BTC which it did able to get to 5 digit price.Hope for long term and patience would really be tested out on this one.
