Altcoin Market Share vs ETH/BTC Setup-Guide for you to bookmark 1) Create a blank chart: e.g. TOTAL/TOTAL*100. You can hide the ticker, we don't need it. 2) Add the ratios one by one (tickers below): Alts (excl. ETH) as % of ETH Marketcap (CRYPTOCAP:TOTAL3-CRYPTOCAP:USDC-CRYPTOCAP:USDT)/CRYPTOCAP:ETH*100 Alts (excl. Top 10) as % of ETH Marketcap CRYPTOCAP:OTHERS/CRYPTOCAP:ETH*100 Alts as % of BTC Marketcap (CRYPTOCAP:TOTAL2-CRYPTOCAP:USDC-CRYPTOCAP:USDT)/CRYPTOCAP:BTC*100 Alts (excl. ETH) as % of BTC Marketcap (CRYPTOCAP:TOTAL3-CRYPTOCAP:USDT-CRYPTOCAP:USDC)/CRYPTOCAP:BTC*100 ETH as % of BTC Marketcap CRYPTOCAP:ETH/CRYPTOCAP:BTC*100 Alts (excl. Top 10) as % of BTC Marketcap CRYPTOCAP:OTHERS/CRYPTOCAP:BTC*100 3) Make sure all of them are on the same scale. What is this? Each colored line represents the percentage share of different altcoin baskets (excluding stablecoins) or ETH relative to either the ETH or BTC market cap (can add more, e.g. SOL or create different dashboards with Memes, AI, DeFi, you name it) What can it be used for? I know: At first glance, this may seem noisy and complex, but it all depends on the questions you want to answer. Once you define those, much of the noise becomes irrelevant, allowing you to simplify the analysis and focus only on what matters to you. What I’ve done here is provide a few initial insights that I found useful (will isolate a couple of them in future). This analysis doesn’t tell you which specific coins to buy, but rather provides a broad market overview as a foundation. It helps guide you toward areas of relative strength or weakness. I’ve included a lot of information here, but the key is to extract the signal from the noise by asking the right questions, for example: At what point do altcoins become overvalued or undervalued against Ethereum? However, when asking these questions, it's important to remember that an overvaluation or undervaluation of Ethereum relative to altcoins tells you little about its valuation against Bitcoin or USD. These are separate questions further down the process.
