Bitcoin $BTC$79,380.27 has surged by 25% to $80,000 in a week. Still, one bastion needs to fall before the bulls can claim victory.
That hurdle is the simple moving average price over the past 50 weeks, currently around $81,087. Historically, reclaiming this level has been one of the clearest signs that a bear market is actually over, not just pausing.
"11 of 13 times BTCUSD reclaimed the 50w MA during completed bear markets, the bear-market low was in. It currently sits around $82k. If BTCUSD reclaims it on weekly close, history suggests the bear market would likely be over," Galaxy Research said.
Moving averages are tracked by traders and analysts to gauge momentum across different timeframes. Among the most widely followed are the 50-, 100-, and 200-period averages across daily, weekly, and other timeframes. Because so many market participants watch the same levels, they tend to become self-fulfilling, acting as real support and resistance simply because enough traders treat them that way.
While the 50-week figure is still out of reach, the price has already blown through all three of the key averages on the daily time frame, in a move Dan Tapiero, the founder of 50T Funds, called an "extreme momentous break up in $BTC and complex." 50T is a multibillion-dollar private growth equity fund investing in mid-to-late stage digital asset companies.
Tapiero added that the cycle low is already in. "Hardest thing to buy here if you aren't long already. Greatest amount of pain is back to 100k immediately,” he noted. Others observers echoed similar sentiments on social media.
Momentum is genuinely strong, but at least one measure suggests markets typically need to catch their breath after a run this hot. That's the seven-day rate of change (ROC), which tracks the rolling percentage move in price over the past week. It currently sits near 25%. (Check the Daily Signal, below.)
Readings at or above that level are rare and have typically been followed by a pullback or a period of consolidation rather than an immediate continuation higher. Stay !
