Bitcoin moved above its 365-day rolling simple moving average near $80,900 on Sept. 22, its first such move in 310 days, according to Altcoin Pro founders Ryan Horst and Joni Zhuleku. In the five previous cases when bitcoin reclaimed the average after spending at least 90 days below it, the price was higher 12 months later, with gains ranging from about 59% to more than 1,400%. The largest increase occurred in 2012, when bitcoin was still a fringe asset. The historical pattern has exceptions: when shorter periods below the average were included, breakouts in July 2018 and March 2022 were followed by declines of about 27% and 59%, respectively, within 90 days. Horst said the latest move is encouraging but needs to hold. The analysts remain bullish over the longer term, though they place greater weight on bitcoin staying above its 200-day average. That average stood near $70,800 in Altcoin Pro's calculations, with bitcoin about 19% above it before a modest decline over the previous 36 hours. The 365-day average was still falling and remained closer to the market price. Moving averages measure past price behavior, and longer averages react more slowly to market changes. Bitcoin's 50-day average also crossed above its 200-day average on Sept. 8, forming a golden cross, a signal with a mixed record as a standalone indicator, CoinDesk's Omkar Godbole wrote.
