A signal that ended most Bitcoin bear markets is flashing again. Bitcoin just closed a weekly candle above its 50-week moving average for the first time in 45 weeks. The close was around $81,159, versus a 50-week MA near $78,786. And historically, this level has mattered. Galaxy Research found that in four of the five completed bear markets that lost the 50-week MA, the first sustained weekly reclaim after the low correctly signaled that the bear market bottom was in. But here's the part I wouldn't ignore: A historical signal isn't a guarantee of the next move. Bitcoin still needs to hold the reclaim. If $BTC can stay above this long-term trend level and momentum continues, attention naturally shifts toward the next major resistance zone — with $90K becoming an obvious level traders will watch. But if Bitcoin falls back below the 50-week average, the breakout could prove less meaningful. So the real question isn't: “Is $90K guaranteed?” It's: “Can Bitcoin turn the 50-week average from resistance into support?” That's the confirmation I'd be watching. 50W reclaim = signal. $90K = next major level. Holding the breakout = the real test. $BTC
