The way and manner of speed ETH bullish at times makes me feels one day, the pump price ratio of ETH may outgrow BTC not in terms of how much is BTC or ETH? But the ratio speed of pumps per bull. I remember 2018 when ETH was less than $150 but ETH takes two weeks to bull market. If somebody should be wise enough ETH would be the next 28k dos.
Past history doesn't guarantee future results. While somethings do follow along the same as it did in the past it's mere coincidence. Following this method will lead you broke. It's quite the opposite really, especially for altcoins. Most times alts don't follow their past rather new altcoins replace some of the older ones. Can eth take over bitcoin, I don't know eth has a lot more competitors than it did in 2018.
Check out the monthly chart for ETH/BTC tho. ETH has slowly been gaining ground since mid 2019 and it's still going tho it's kinda choppy starting around June 2021. Does that mean there's going to be a flippening for ETH and BTC? Who knows... But could anybody say that BTC is going to stay the top dog of crypto forever in terms of market cap? Saying yes would be sketchy imho, because again... Who knows.
But I'm pretty sure maxis would say so without any real convincing arguments backing up the claim, just faith.
