Fear & Greed Index for CoinGecko

Shows the crypto Fear & Greed Index from alternative.me inside CoinGecko (homepage & Bitcoin page).

What it is A cross-browser browser extension (Chrome/Edge/Brave and Firefox) that surfaces the crypto Fear & Greed Index from alternative.me directly inside CoinGecko, so you don't have to leave the site to read market sentiment. Where it appears Homepage (/, /en, any locale root): injected as a card immediately after the 24h Trading Volume card, in the same responsive stats column — same design language as CoinGecko's own stat cards. Bitcoin page (/en/coins/bitcoin): injected as a stat line directly under the Market Cap row, matching the existing stats-table style (label on the left, value + classification on the right). No card here, per your request. In both places it shows: The numeric index (0–100) The classification (Extreme Fear → Extreme Greed), colored to match CoinGecko's red/green palette A small conic-gradient gauge on the homepage card (linking to alternative.me) An info tooltip (ⓘ icon) explaining how the index is calculated
