Bitcoin is once again drawing major attention from analysts and investors as it holds strong above the $90,000 level, showing signs of a sustained bull run. For the past week, the world’s leading cryptocurrency has gained over 11%, and now a familiar historical pattern—Bitcoin’s four-year cycle—is fueling speculation that the price could reach as high as $131,000 by mid-October.

One of the strongest signals backing this outlook is Bitcoin’s position above its Short-Term Holder (STH) Cost Basis, currently at $93,145. This metric represents the average acquisition price for short-term investors and is often used to gauge whether Bitcoin is in a bullish or bearish phase. When BTC trades above this line, it tends to signal ongoing bullish momentum, as short-term holders are in profit and less likely to sell under pressure.

The wider range within this cycle includes a lower support zone near $71,150 and an upper resistance area at $131,800. Bitcoin’s current positioning in the upper half of this band reinforces the idea that the asset is trending toward the top of its market range—if momentum continues and no significant resistance derails the run.

In addition to price patterns, on-chain data supports a bullish thesis. Over the past 48 hours alone, nearly 20,000 BTC—worth approximately $1.86 billion—has been bought up from exchanges. This large-scale accumulation is considered a powerful upward catalyst. Typically, such buying pressure reduces available supply and supports price appreciation, especially when market sentiment is positive.

Adding more weight to the bullish case is a recurring fractal pattern that Bitcoin has historically followed. Since 2015, this pattern has repeated across four major cycles and has helped accurately pinpoint both market tops and bottoms. According to analysis by Alphractal, Bitcoin is currently in the “markup phase”—a period characterized by rapid gains after a phase of accumulation. If history is any guide, the top of this phase is expected to be reached between October 12 and October 16.

In previous cycles, Bitcoin’s rallies during this phase ended with significant gains, followed by a cooling-off period or decline. Should the pattern hold true once again, it positions BTC to hit the $131,000 range just before the cycle peaks in mid-October.

Technical indicators on longer timeframes further strengthen the bullish narrative. On the monthly chart, Bitcoin has bounced off a long-standing ascending trendline that dates back to 2018. Each time Bitcoin has tested this support, it has initiated major rallies. Analysts now believe that breaching the next major resistance level at $102,000 could trigger a fresh leg upward, potentially opening the door to new all-time highs.

Although markets are never guaranteed to follow historical patterns precisely, the alignment of technical levels, accumulation data, and fractal cycles offers a compelling case for Bitcoin’s continued rise. If Bitcoin maintains its current momentum and breaks above key resistance points, hitting $131,000 by October may no longer be just a bold prediction—it could become a reality investors are preparing for.

The coming weeks will be critical, with both retail and institutional investors watching closely to see whether Bitcoin’s bullish trend holds. If the four-year cycle proves consistent once again, this could mark one of the most dramatic and lucrative phases of the 2025 crypto market.
