Alternative’s Crypto Fear and Greed Index reached 78 on September 22, entering the extreme-greed zone for the first time since July 12 last year. The reading placed cryptocurrency-market sentiment at its highest level in more than a year. A separate CoinMarketCap gauge previously stood at 79, up seven points from the prior day and still in greed territory. CoinMarketCap’s index uses price movements among the 10 largest cryptocurrencies, market volatility, derivatives indicators including the put/call ratio, the stablecoin supply ratio and search activity, so the two providers’ readings are not identical measures.
