Bitcoin's chart just flashed a red signal — and it is not about price. CoinDesk reports the Guppy Multiple Moving Average has turned bearish: Bitcoin's price has dropped below both moving-average bundles, and the short-term bundle has slipped below the long-term one. The long-term lines are now squeezing together and starting to slope downward. That is the textbook shape of a trend losing its floor, not a single bad day. Bitcoin sits near $76,800, down about 1.8% on the day, after slipping below $77,000. A red GMMA does not call the bottom. It says the trend itself has flipped — and traders now wait for the chart to prove it wrong.
