The cryptocurrency market has experienced significant volatility in recent weeks, with Bitcoin [BTC] dropping below the psychologically important $60,000 mark. While this downturn has affected the broader digital asset landscape, it may also be laying the groundwork for a potential bull run—particularly as we approach September, a month historically associated with bearish trends in financial markets.
Yet, contrary to past patterns, several key on-chain and technical indicators suggest that 2025 could break the cycle. This year, September might mark not a market decline, but the beginning of a powerful upward movement in crypto prices. Below are five compelling signs pointing toward a possible cryptocurrency bull run this September.
Declining Exchange Reserves Signal Strong Holder Confidence
One of the most reliable indicators of an upcoming bull market is the consistent decline in Bitcoin and Ethereum [ETH] reserves held on centralized exchanges.
When coins are moved off exchanges and into private or cold storage wallets, it reflects a growing trend of long-term holding rather than active selling. This reduces the available supply on trading platforms, creating scarcity—a fundamental driver of price appreciation.
As of mid-2025, Bitcoin’s exchange reserves stand at approximately 2.62 million BTC, continuing a steady downward trajectory observed since late 2024. Similarly, Ethereum’s exchange holdings have dropped to around 18.7 million ETH.
This sustained outflow indicates that investors are "hodling" through volatility, likely anticipating higher prices ahead. Historically, such accumulation phases precede major rallies, making this a strong foundational signal for a potential bull run.

Market Sentiment: Fear Paving the Way for Greed
Market psychology plays a crucial role in predicting trend reversals. The Crypto Fear & Greed Index, which measures investor sentiment across various metrics including volatility, volume, social media activity, and surveys, currently sits in the “Fear” zone.
While fear may seem negative, it often presents contrarian buying opportunities. Periods of extreme fear typically coincide with capitulation—when weak hands sell off assets at low prices—clearing the path for recovery and renewed bullish momentum.
Historically, shifts from fear to greed have preceded major bull runs. For instance, similar sentiment levels were observed in late 2023 before the explosive rally in early 2024. With sentiment now bottoming out again, the stage could be set for a reversal.
When confidence returns and greed begins to build—especially if triggered by macroeconomic improvements or regulatory clarity—the market could see rapid upward movement.
MVRV Ratio Shows Assets Are Deeply Undervalued
The Market Value to Realized Value (MVRV) ratio is a powerful metric used to assess whether Bitcoin or Ethereum is overvalued or undervalued relative to its historical cost basis.
A MVRV below 1.0 suggests that the current market value is lower than what investors originally paid—indicating widespread unrealized losses and potential oversold conditions. A reading below zero implies that holders are collectively underwater.
Currently, Bitcoin’s 180-day MVRV stands at approximately -9.6%, meaning long-term holders are sitting on average losses exceeding 9%. Meanwhile, Ethereum’s MVRV has remained negative since July 2025 and now hovers around -23%—a sign of even deeper undervaluation.
These levels are historically significant. In prior cycles, prolonged periods of negative MVRV were followed by strong recoveries once sentiment improved and demand returned. With both assets trading well below their real value, the conditions appear ripe for a correction to the upside.
Key Support Levels Hold – Technicals Favor a Reversal
Technical analysis further supports the possibility of a bullish breakout. Bitcoin has been trading below both its 50-day and 200-day moving averages, reflecting short-term bearish momentum.
However, price action near key Fibonacci retracement levels suggests resilience:
- The 61.8% retracement level at $52,016 has acted as strong support. Bitcoin has tested this zone multiple times and consistently rebounded, signaling strong buyer interest.
- A sustained hold above this level increases the likelihood of a resumption in upward momentum.
- More importantly, a breakout above the 38.2% retracement level at $58,140 could trigger aggressive buying pressure from algorithmic traders and institutional players alike.
In past cycles, such technical breakouts—especially after extended consolidation phases—have often marked the start of new bull legs. With volume beginning to stabilize, the technical setup is increasingly favorable.
Rising Open Interest and Volume Could Ignite the Next Leg Up
Two critical derivatives market indicators—open interest and trading volume—also provide clues about future price direction.
Earlier in 2025, during the peak of the previous bullish phase in March, Bitcoin reached an all-time high near $73,000. At that time:
- Open interest surged past $75 billion
- Daily trading volume exceeded $199 billion
Since then, both metrics have pulled back significantly—open interest dropped to around $50 billion**, and volume declined to roughly **$100 billion—typical behavior after a major top.
But here’s the key: a renewed rise in open interest alongside increasing volume would signal fresh capital entering the market, especially if accompanied by price stabilization or gains. Such a confluence often precedes explosive moves.
If these derivatives metrics begin climbing again in August or early September—particularly as spot market sentiment improves—it could act as rocket fuel for a new bull run.

Frequently Asked Questions (FAQ)
Is September usually good or bad for crypto?
Historically, September has been one of the weakest months for cryptocurrency performance, often marked by sell-offs following summer rallies. However, market cycles evolve—and with strong fundamentals now in place, 2025 could defy seasonal trends.
What does declining exchange reserve mean for prices?
When coins leave exchanges, they become less available for immediate sale. This reduces selling pressure and increases scarcity, which can drive prices up when demand returns.
How reliable is the MVRV ratio in predicting bull markets?
The MVRV ratio has proven highly effective in identifying major market bottoms. Negative MVRV readings have preceded nearly every major bull run since 2015, making it one of the most trusted long-term valuation tools.
Can fear really turn into a buying opportunity?
Yes. Market extremes often create emotional selling. Investors who buy during periods of fear—when prices are low and sentiment is poor—typically benefit most when optimism returns.
What happens if Bitcoin breaks above $58,000?
A confirmed breakout above $58,140 (the 38.2% Fibonacci level) could trigger algorithmic buying and force short sellers to cover positions, accelerating upward momentum toward $65,000 and beyond.
Should I invest before September?
Timing the market perfectly is difficult. However, with multiple indicators suggesting accumulation and undervaluation, positioning early—with proper risk management—could offer strategic advantages ahead of a potential rally.
Final Outlook: A Bull Run Is Taking Shape
Despite short-term price weakness and seasonal headwinds, the underlying data tells a compelling story: a new cryptocurrency bull run could ignite as early as September 2025.
Key factors—including shrinking exchange reserves, deeply negative MVRV ratios, supportive technical structures, recovering derivatives activity, and fearful market sentiment—are aligning in a way rarely seen outside of major turning points.
Bitcoin and Ethereum continue to lead the ecosystem’s direction. Their current behavior suggests we may be in the final stages of accumulation before the next phase of growth begins.
Whether you're a long-term holder or an active trader, now is the time to monitor these signals closely—and prepare for what could be one of the most significant market movements of the cycle.
