Why did BTC fall below 100k today?

BTC fall below 100k, and the entire crypto market felt the shock. Traders woke up to screens filled with red, liquidations running wild, and sentiment flipping almost overnight. It wasn’t one of those slow, predictable dips either. This move hit fast, caught overleveraged positions off guard, and left investors asking what triggered such an aggressive sell-off.

BTC fall below 100k line isn’t just about charts or technical levels. It’s tied to bigger pressures coming in from global markets, tightening liquidity, and a sudden shift in institutional flows. With risk appetite fading and funding stress rising, the drop feels less like a random correction and more like the outcome of several forces hitting at once.

A sudden liquidity squeeze

One of the biggest forces behind the drop is a liquidity crunch. Markets are feeling the strain, and that’s hurting risk assets like Bitcoin. Funding conditions have tightened, and traders are steering away from aggressive bets when cash is getting harder to access.

As BTC fall below 100k, trading activity spiked — but not because new buyers stepped in. The surge came from a wave of forced liquidations that pushed the market even lower. In the past 24 hours alone, more than $1.10 billion in positions were wiped out, with $969 million coming from longs. BTC accounted for over $509 million by itself, while ETH added another $266.9 million. Solana followed with about $69.8 million, and the rest of the market contributed roughly $78.5 million.

More than 246,000 traders were liquidated in the same window, including one massive $44.29 million BTC-USDT position on HTX, the largest single liquidation of the day. With that kind of forced selling pressure, the slide wasn’t just likely; it was almost unavoidable.

Macro risk kills risk appetite

Another key reason why did BTC fall below 100k today is macro uncertainty. Investors are growing uneasy about global economic risks. There are rising doubts about whether central banks will ease soon, despite previous hopes for rate cuts. That makes risky assets like Bitcoin less attractive right now.

Specifically, expectations regarding a December rate cut by the U.S. Federal Reserve are cooling, and with fewer signals indicating imminent monetary easing, many traders are stepping back from high-volatility bets. And while there are hostilities in the U.S. short-term funding markets, it is not necessarily an extremely attractive backdrop for leveraged trades. 

The overall risk-off sentiment has spread to crypto. Investors are fleeing to safer assets, and Bitcoin is absorbing that impact.

ETF outflows and institutional pullback

Structural flows are playing a big role too. Several reports suggest that U.S. spot Bitcoin ETFs reversed course midweek, swinging from large inflows to heavy outflows. This shift undercuts a core pillar of this bull market, regulated institutional demand. When ETFs bleed capital, it sends a strong signal that even big players are stepping back.

At the same time, long-term BTC holders appear more willing to sell into weakness. On-chain data points to increased distribution among whales and treasury holders. That’s raising fresh questions: if long holders are letting go, who’s left to catch the fall?

Recent whale-selling patterns are also shaping short-term price action, and a deeper look at their Q4 behaviour can help explain this shift. You can read that breakdown here.

Leverage amplifies the move

Leverage is always a double-edged sword. On the way down, it’s very painful. As BTC cracked key support, forced liquidations accelerated. Many leveraged long positions were wiped out, creating a cascading effect. With so many players leveraged, the breakdown triggered more selling than a simple price pullback.

This cascade helps explain the speed and severity of the drop. It wasn’t just technical traders reacting; it was a washout driven by forced exits.

What comes next?

With Bitcoin trading under the $100,000 mark, the next few days could be significant. Analysts are looking at key support around $93,000 to $95,000. If those break, we could see more downside. But if macro conditions improve, for example, renewed rate cut optimism or a liquidity injection, we could see a rebound.

ETF flows will remain a key risk factor. Continued outflows could pressure prices further. On the other hand, if institutions step back in, they might stabilize things.

Another angle to watch is long-term holder behavior. If big players stop distributing and switch back to accumulation, that could signal that the shakeout is over.

Final word

So, why did BTC fall below 100k today? There isn’t a single smoking gun. It’s the mix that did the damage: tighter liquidity across markets, risk-off sentiment creeping in, ETF outflows picking up speed, and a wave of leveraged positions getting flushed out. When all of that hits at once, even Bitcoin feels the weight.

Still, this drop doesn’t automatically signal the end of the broader cycle. Markets have seen deeper corrections and bounced back stronger. Bitcoin has also shown, time and again, that it can recover quickly once funding stabilizes and buyers step back in. Institutions haven’t disappeared. Retail hasn’t vanished. The long-term bullish arguments around supply, adoption, and halving dynamics are still in place.

For now, the mood is shaky, and traders are defensive. But if liquidity eases and flows return, the market could settle faster than expected. The next few days will tell us whether this was a short, sharp reset or the start of a deeper shift. Either way, the move under 100k will go down as another reminder that Bitcoin still moves on its own terms, and usually when people least expect it.
