Frequently Asked Questions
Everything you need to know about CoinTrendz Radar, the Fear & Greed Index, and how to use crypto sentiment data effectively.
What is the Fear & Greed Index and how is it calculated?
The Crypto Fear & Greed Index is a composite sentiment indicator that measures the overall emotional state of the cryptocurrency market on a scale from 0 (Extreme Fear) to 100 (Extreme Greed). It is calculated daily by Alternative.me using five weighted factors: market volatility (25%), market momentum and volume (25%), social media activity (15%), surveys (15%), and Bitcoin dominance (10%). Understanding the methodology behind the index helps investors interpret it correctly — a high volatility reading suggests panic, while high momentum combined with high social activity suggests speculative excitement. A score below 25 indicates extreme fear, 25 to 45 is fear, 46 to 55 is neutral, 56 to 75 is greed, and 76 to 100 is extreme greed.
How often does the data on CoinTrendz Radar update?
CoinTrendz Radar auto-refreshes all market data every 60 seconds. Every minute, the platform fetches fresh data from the CoinGecko API and Alternative.me API to update price information, percentage changes, market capitalization, 24-hour trading volume, top gainers, top losers, and trending coins. A real-time countdown timer is displayed in the dashboard's status bar at all times so you can see exactly how many seconds remain until the next automatic update. You do not need to manually refresh the page — the dashboard handles this entirely on its own, making it ideal for monitoring open on a secondary monitor or browser tab throughout the trading day.
What does each sentiment level mean for investors?
Each zone of the Fear & Greed Index reflects a distinct market climate with different implications for investors. Extreme Fear (0–24) often correlates with panic selling, capitulation events, or major negative news. Historically, these periods have sometimes offered value for disciplined long-term buyers willing to act against the crowd. Fear (25–45) suggests negative sentiment but not full panic — prices may still be declining but conditions are less extreme. Neutral (46–55) reflects a balanced market without strong directional momentum. Greed (56–75) suggests rising optimism and positive momentum, though valuations may be stretching. Extreme Greed (76–100) has historically preceded sharp corrections as enthusiasm outpaces fundamentals. These patterns are observations drawn from historical data, not guarantees, and should never be your sole basis for investment decisions.
How can I use CoinTrendz Radar to make better investment decisions?
CoinTrendz Radar is a context tool, not a signals service. Many experienced investors use the Fear & Greed Index as one input among many in a contrarian strategy: accumulating positions gradually during periods of extreme fear (when price drops may represent value) and reducing exposure during periods of extreme greed (when risk is elevated). The Top Gainers table is useful for identifying coins showing strong short-term momentum that you may want to research further. The Trending Coins section helps you discover emerging narratives early before they reach mainstream attention. The BTC and ETH sparkline charts provide quick visual confirmation of the overall market direction. We recommend combining CoinTrendz Radar data with on-chain analysis, fundamental research, and sound risk management principles. Nothing on this platform constitutes financial advice.
Where does the cryptocurrency data come from?
All cryptocurrency price, market cap, volume, and trending data is sourced from the CoinGecko public API. CoinGecko is one of the world's largest independent cryptocurrency data platforms, aggregating data from over 900 exchanges and tracking more than 14,000 coins. Their data pipeline normalizes pricing across exchanges to deliver consistent, reliable market data. The Fear & Greed Index is provided exclusively by Alternative.me, which has computed and published this metric every day since 2018. CoinTrendz Radar is an independent tool and is not affiliated with, endorsed by, or officially partnered with CoinGecko or Alternative.me. We display their public data to help users access it more conveniently.
How are Top Gainers and Top Losers determined?
CoinTrendz Radar retrieves data on the top 250 cryptocurrencies ranked by market capitalization from the CoinGecko API. We then sort these coins by their 24-hour percentage price change. The ten coins with the largest positive percentage movements are listed in the Top Gainers table, and the ten with the largest negative movements appear in the Top Losers table. Filtering to the top 250 by market cap ensures that the results reflect coins with meaningful liquidity and real market activity, rather than obscure micro-cap or low-volume tokens where extreme percentage changes may result from thin order books and manipulation. Both tables display the coin name, ticker symbol, current price in USD, and the precise 24-hour percentage change.
What are Trending Coins and why do they matter?
The Trending Coins section displays the seven coins that have received the highest search volume on the CoinGecko platform over the past 24 hours. When a coin suddenly enters the trending list, it often signals a surge in community and retail interest that may be driven by news, social media discussion, a new product launch, or a notable price move. Trending status is a powerful leading indicator because retail investor attention frequently precedes price activity. By monitoring trending coins daily, you can stay informed about emerging narratives and make more timely research decisions. That said, trending status alone does not confirm quality or long-term value — always investigate the reason a coin is trending before making any investment decision.
