Bitcoin Dominance Widget
Show how much of the crypto market is Bitcoin. The Bitcoin dominance widget splits the total market cap into BTC, ETH and everything else on a live donut, each with its percentage, then ranks the biggest coins by share and plots how dominance has moved over the past year. It reads the live market caps of the top coins — the same feed Vunelix uses on its own pages — and drops into any site with no signup and no API key.

The Market at a Glance
Bitcoin dominance is one number that says a lot: when it rises, money is flowing into BTC; when it falls, altcoins are gaining. The donut shows the split — Bitcoin, Ethereum and the rest — so a reader sees the balance of the market instantly, with each slice labelled by its percentage share.
Coin-by-Coin Breakdown
Under the donut, ranked bars break the market down coin by coin — BTC first, then ETH and the largest alts — each with its share of the total. It turns "Bitcoin is 54%" into the full picture of who holds the rest.
Dominance Over Time
A history chart plots Bitcoin dominance across the past year, so the current reading has context — is BTC gaining ground on the alts, or losing it? The line makes the trend obvious, not just today's number.
