I think Ethereum has no chance to outperform its ATH in relation to bitcoin, there is too many delays and too many competitors for ETH to repeat its peak.
Money floated away f.e. to BNB, EOS etc..
Nonetheless I am waiting for Ethereum price increase soon but I think we won't see ETH over 1000usd (at least until bitcoin will reach ~50k USD level..)
I hope you will be wrong, for me, I believe it doesn't need for bitcoin to reach 50K usd for ETH to reach $1,000.
If that's what you believe, you believe that while bitcoin is rising, ETH will just stay the same level of movement now.
The current price now is 13K usd, so BTC needs an increase of 3.84 folds to reach 50K and if ETH will just stay at the current it would reach over $1,000 that time. I guess ETH can't hold that long, there's a FOMO that time and every time there's a FOMO ETH also get the benefits.
