Fear & Greed

• It's the Fear & Greed Index published by Alternative.me once a day. We don't calculate it: we show it as is, with its source alongside.
• It sums up Bitcoin market mood from volatility, price volume and momentum, social media chatter, Bitcoin's share of the total market and Google searches.
• The zones are the source's: 0 to 25, extreme fear; 26 to 46, fear; 47 to 54, neutral; 55 to 75, greed; and 76 to 100, extreme greed.

Not on its own. It tells you the market's mood, not where the price will go. Lots of fear can last for weeks, and so can lots of greed. Use it as one more data point, never as a signal.

Once a day. The source publishes the new value shortly after midnight UTC, and it shows up here within an hour or two.

Since February 2018, day by day. With your account activated (your UID linked and at least 100 USDT in your exchange) you see all of it, with the average, low, high and how many days it spent in each zone.
