Bitcoin dominance is one of those metrics that confuses a lot of new traders, so I went looking for a solid explanation. Found a really useful Crypto Guide by Paybis https://paybis.com/blog/glossary/what-is-bitcoin-dominance/ that breaks it down without overcomplicating things. It explains what dominance actually measures, why it matters for altcoin performance, and how experienced traders use it to read broader market cycles. The writing is clear and doesn't assume you already know everything, which is rare in crypto content. Understanding this metric genuinely changed how I read market conditions — when dominance spikes, I know altcoins are likely bleeding, and vice versa. If you're trying to move past basic buy-and-hold strategies, getting your head around dominance is a worthwhile step. That guide is a good place to start.
