I really do not see that kind of rally coming up in ETH,it had its rally in the past,when it was below ten dollars and had a big rally when projects started using them and now we have reached over $400 which i think is a pretty decent valuation for the coin which has no limits. The best valuation i expect is $1000 and not more than that for now.
ETH grows very fast, I think it would be higher than $1000,,, but I also believe that it wont be as high as $5000-$10000 because that was too high...
If we see ETH price theese last 3 months, I think $2000-$3000 is a realistic target for us to hope ~
