Bitcoin Defies Statistics and Marks a Historic September

September, the month that often rhymed with bloodbath for bitcoin, finally changes its course. Traditionally called “Rektember” by traders, it was synonymous with brutal crashes and discouragement. But in 2025, the king of cryptos has surprised everyone. When we talk about macroeconomics, regulation, and the Fed, a review is necessary: did BTC really hold up this month? The answer seems clear: yes.

When “Rektember” becomes a month of glory for bitcoin

Historically, September was the worst month for the bitcoin price with an average loss of 8%. But this year, the scenario flipped. BTC shows an 8% increase , making it the best September since 2012, when the rise reached nearly 20%. Data from CoinGlass and BiTBO confirm this record.

This trend reversal is all the more intriguing because volatility is surprisingly low. In 2025, bitcoin price fluctuations are at levels not seen in over a decade. Drawdowns remain limited: –30% at worst, compared to –80% in past cycles. 

The bullrun truly exists, but it does not resemble previous ones. This relative stability intrigues as much as it reassures, as it suggests a new maturity for the asset.

The Fed blows hot and cold on crypto

Behind these performances, the shadow of the Fed looms. With the expectation of a 25 basis points rate cut and declining inflation (August PPI at 2.8%), investors regained appetite. 

Institutional flows prove it: Bitcoin ETFs attracted 757 million dollars in a single week, while Ethereum also benefits from a renewed demand.

But the suspense remains. Bitunix analysts warn: a “dovish” tone from Jerome Powell could propel BTC to 118,000 dollars. Conversely, a speech too “hawkish” would trigger a brutal correction.

The domino effect: when bitcoin’s momentum drives the entire crypto market

The September rebound is not limited to bitcoin, the crypto market shows gains . Its capitalization climbed to 4.16 trillion dollars (+1.1%), while 84 of the top 100 cryptos showed green. Ethereum trades around 4,544 dollars, BNB rises 2.8%, and XRP surpasses the symbolic 3 dollars mark.

Another sign of confidence: Banco Santander launched crypto trading via Openbank, opening the way for broader banking adoption. And while Wall Street accumulates BTC via ETFs, the UK and the US are aligning their regulatory frameworks, especially around stablecoins and anti-money laundering. An unprecedented coordination could transform the ecosystem.

Some figures that speak for themselves

• Bitcoin posts +8% in September 2025, record since 2012;
• 757 million $ inflows into Bitcoin ETFs in one week;
• Crypto market cap: 4.16 trillion $ with 84 of the top 100 tokens up;
• Ethereum reaches 4,544 $, XRP climbs to 3.02 $, BNB to 954 $.

Bitcoin broke the September curse and gave unexpected breath to the crypto market. Yet, another story is already brewing. If October is often seen as “uptober”, some analysts see the shadow of a crash looming. A fractal model recently identified raises fears of an imminent correction.
