Bitcoin Down: Why This Week Is Crucial to Close 2025

Bitcoin has just fallen below $84,000, a threshold that raises questions among investors. This drop occurs in a tense economic context, where selling pressures and macroeconomic uncertainties weigh heavily. This week promises to be decisive in determining whether 2025 will close in red or green.

Why Is Bitcoin Collapsing Below $84,000?

Bitcoin starts December 2025 with a sharp drop to $84,000. A collapse explained in part by the selling pressure exerted by institutional players on Wall Street. Indeed, from the opening of the US markets, massive sales accelerated the decline, reducing available liquidity and amplifying price movements. Investors, already nervous, reacted by liquidating their positions, worsening the downward trend.

In Asia, adverse macroeconomic headwinds played a key role. The rise in interest rates in Japan and geopolitical tensions reduced liquidity, creating an unfavorable environment for risky assets like bitcoin. Cascade liquidations triggered by margin calls then amplified the drop, turning a correction into a deeper movement.

Finally, the end of “Quantitative Tightening” in the United States, though supposed to favor risk assets, has not yet had the expected effect on bitcoin. Capital flows remain cautious, and investors await clearer signals before repositioning massively on cryptocurrencies.

Which Levels Will Tip BTC in December 2025?

The $85,200 and $87,000 levels are now under close watch following bitcoin’s fall to $84,000. The first, $85,200, represents a critical support: if bitcoin fails to hold there, a new wave of selling could drive the market to new lows. Conversely, a rebound above this threshold could indicate a gradual stabilization.

The second level, $87,000, is just as crucial. Crossing this mark would allow bitcoin to retest the weekly open and give a positive signal to investors. They must therefore remain vigilant, as a break below $85,200 could dash hopes of a rebound and extend the downtrend.

Bitcoin in December: Is a Down Start a Good Omen?

Historically, December has often been a volatile month for bitcoin. In 2017 and 2020, this period was marked by spectacular rallies, while in 2018 and 2022, corrections dominated. For this year, predictions for December are mixed. Some analysts, like Ryan Lee from Bitget Research, believe BTC could soar to $100,000:

Despite the pullback, the underlying structure remains constructive. If the Federal Reserve adopts a more accommodating tone under new leadership, expectations of rate cuts could fuel a new rally, potentially driving bitcoin to $110,000.

Accordingly, Michaël van de Poppe fairly believes that this drop in bitcoin could offer a buying opportunity at a low price.

On the other hand, others, more pessimistic, fear a continuation of the fall, especially if key levels do not hold. The general sentiment thus remains mixed, between fear and opportunism.

This week is decisive for bitcoin, with key levels to watch and macroeconomic factors to consider. Between opportunities and risks, December 2025 promises to be a pivotal month for BTC. Will bitcoin manage to reverse the trend or does this drop herald a prolonged crypto winter?
