BofA revises BoE rate cut forecast to quarterly pace
Ethereum had a rough beginning of 2025—failing to reach new all-time highs, while Bitcoin smashed through its own ATH multiple times. Solana, providing a cheaper alternative to ETH services, also held stronger than the Ether throughout the latter part of 2024 and beginning 2025.
ETH performance is key to the overall crypto market performance; the past Altcoin cycles have always been led by ETH performance over BTC.
ETH/BTC is a great cryptocurrency spread for a crypto trader to spot relative performance, provide a direction for which crypto to choose, and track the appetite for altcoins.
Through this Crypto Market Update, you will see how ETH/BTC rising helped altcoin bull-runs in the past cycle, something that many crypto traders have been awaiting and is yet to materialize again.
ETH/BTC and its Correlation to total Market Performance

This 2017 to 2021 chart of ETH/BTC contains essential information about understanding the Crypto Market.
Through 1 and 2 we observe how the first bull run in ETH and ETH/BTC led to the 2017 Total Crypto Market bull run - taking the Market Cap from $20B-$30B average to highs of $620B in November 2017.
Number 3 on the chart shows how a drop in ETH/BTC leads to a significant cool down of the Crypto Market, going back towards a total market cap between $100 to $250B from 2018 to the end of 2020.
From end 2020 to the end of 2021, number 4 shows the same correlation of ETH/BTC and Crypto markets rallying.
This Covid-Era bull run introduced crypto for an ever-bigger number of investors, and led to the flurry of altcoins and cryptocurrency projects such as Doge, Avax, Solana. The Crypto Market cap went from $300B to $2.86T, this level only got reached again in November 2024.
Finally, number 5 shows similarly to number 3 how the drop in Market Cap correlates with a drop in the ETH/BTC spread.
ETH/BTC from 2020 to Today

We take a closer look at the 2021 Bull Run and how the December 2021 top in ETH/BTC led again a significant correction in the Crypto Market.
2023 was all about Bitcoin Dominance as its rally from $14,475 to its record highs of $112,030 left Ethereum and all other altcoins lagging.
