Bitcoin bear market durations historical cycles show prior stretches of 406 days, 362 days and 398 days while this cycle has reached only 267 days so far according to @simplykashif. BTC price prediction models must now factor why current Bitcoin cycle may differ from 2018 or 2022 as the shorter duration points to structural shifts in liquidity and institutional flows. On the 4h chart BTC trades at $83868.5 inside Bollinger Bands with upper resistance at $88167.19 and lower support at $82049.32 while EMA50 at $82329.81 and EMA200 at $77169.19 define the bullish trend structure; despite the MACD death cross at 789.38 the neutral RSI at 50.17 keeps price action constructive above the 50-EMA confluence zone before any test of upper band volatility exhaustion.
