$BTC AT $81K: A 77% CLIMB TO $143K MODELED TREND Over the past 90 days: • 400-day cycle average: down 9.5% • 1,510-day structural average: up 5.2% The cycle has weakened while the longer-term average keeps rising. That’s the bullish case: if the structural trend persists, BTC benefits from both closing today’s valuation gap and continued growth in the trend itself. The opportunity is a recovery toward a rising trend.
