Imagine this: Bitcoin has just pulled back from its latest all-time high, dipping sharply enough to make even seasoned holders sweat a little. Yet, instead of spiraling into a prolonged bear market, it finds solid ground and starts climbing again—delivering gains north of 60% in just half a year. Sound familiar? If you’ve been following crypto for the past couple of years, it should.
That’s the intriguing pattern that’s emerged since spot Bitcoin ETFs hit the scene. And right now, as we sit in mid-December 2025 with BTC trading around $90,000, many analysts believe we’re seeing this cycle reset once more. It’s got bulls excited about another big rebound, but there are real risks lurking that could derail the ride.
In this deep dive, I’ll break down what’s driving this optimism, why the old halving-driven four-year cycles feel increasingly outdated, and what could potentially spoil the party. Let’s get into it.
The New Era: ETF-Driven Cost-Basis Cycles
For years, the crypto community lived and breathed by the four-year halving cycle. Reduced supply, growing demand, parabolic rallies—it was almost clockwork. But something shifted dramatically in 2024 when spot ETFs opened the floodgates for institutional money.
Suddenly, Bitcoin wasn’t just a speculative asset for retail traders. It became part of balanced portfolios managed by financial advisors and institutions. And that brought a new dynamic: rebalancing.
When BTC surges into price discovery, its weighting in those portfolios balloons quickly. A modest 2-5% allocation can double or more in months. Institutions don’t let that happen—they sell portions to lock in gains and maintain risk parameters. The result? Sharp corrections that reset the price closer to the average cost basis of ETF holders.
Then, once the dust settles, fresh capital flows back in, and the upward expansion resumes. This “cost-basis returns cycle” has played out reliably three times already since early 2024.
Price breaks to new all-time highs, corrects sharply, and then finds support almost perfectly at the ETF investor cost basis before beginning the next leg up.
Each of those legs delivered returns exceeding 60% within roughly 180 days. If history is any guide—and in markets, patterns like this often persist until they don’t—we could be on the cusp of another substantial rally.
Where Are We in the Cycle Right Now?
As of December 15, 2025, Bitcoin is trading just under $90,000 after bouncing from lows around $87,600. That’s classic range-bound action following a consolidation phase.
More importantly, the current price sits very close to the estimated average cost basis for spot ETF investors. In past cycles, this level acted like a magnet for support—buyers stepped in aggressively, viewing it as a discounted entry relative to recent peaks.
From here, if the pattern holds, we could see BTC grind higher, attract new inflows, and eventually break out toward fresh all-time highs. Some projections, factoring in rising cost basis as more capital enters, point to targets well into six figures over the coming months.
I’ve always found these institutional-driven patterns fascinating. They’re less emotional than retail cycles and more tied to cold, calculated portfolio mechanics. In a way, it’s Bitcoin maturing—volatility being harvested systematically rather than chaotically.
Why Institutions Aren’t “Hodling” Like Retail
One key insight: most institutional players aren’t in Bitcoin for ideological reasons. They don’t care about “stacking sats” or decentralization narratives the way early adopters do.
Instead, they’re treating it as an asset class contributing to overall portfolio returns with acceptable risk. That means regular rebalancing becomes essential.
- A 2% allocation can grow to over 6% in under six months during strong rallies.
- A 5% starting position might approach 10-15% without trimming.
- Financial advisors have mandates to keep alternative assets within tight bands.
So those sharp drawdowns we’ve seen? They’re often institutions taking profits and resetting exposure. It’s not panic selling—it’s disciplined risk management turning Bitcoin’s volatility into realized gains.
Once rebalanced, the cycle can restart as new allocations flow in or existing ones get topped up at lower prices.
The Bull Case: Another 60%+ Move Ahead
If we’re indeed at the support phase of this cycle, the historical precedent is compelling. Three prior instances, three big rebounds.
Bulls argue that nothing fundamental has changed: ETFs continue accumulating (even if inflows have slowed recently), global liquidity remains accommodative overall, and Bitcoin’s narrative as digital gold persists.
Moreover, as the cost basis creeps higher with each cycle—reflecting ongoing institutional adoption—the eventual premium expansion could drive even larger absolute gains than before.
Picture this: starting from around $90K, a 60% move takes us past $144,000. Stretch it further if inflows accelerate again, and suddenly $150K+ enters the conversation. It’s not guaranteed, of course, but the setup looks eerily similar to previous turns.
The Risks: Why This Time Could Be Different
Of course, markets don’t repeat exactly forever. There are several headwinds that make this cycle feel more fragile than prior ones.
First, ETF inflows have notably cooled in recent months. After massive volumes earlier in the year, December data shows significantly reduced net buys. If outflows dominate for a sustained period—especially from major players like BlackRock or Fidelity products—the price floor could weaken.
These ETFs now represent a meaningful chunk of total Bitcoin ownership. Sustained redemptions would force actual BTC sales into the market, potentially breaking below cost-basis support.
Macro Uncertainty and Fed Policy
The Federal Reserve’s stance adds another layer of caution. Recent rate cuts were largely priced in, and projections now suggest only limited easing ahead—perhaps just one more in 2026.
Risk assets like Bitcoin tend to thrive in low-rate, high-liquidity environments. If central banks turn more hawkish—or if other major players like the Bank of Japan tighten unexpectedly—crypto could face broader selling pressure.
Thin holiday liquidity around year-end could amplify any negative moves. We’ve seen flash crashes in quiet periods before.
Corporate Treasury Risks: The Strategy Example
Then there’s the growing role of corporate treasuries holding Bitcoin. One prominent company has amassed over 3% of total supply, largely through debt-financed purchases.
While this demonstrates conviction, it also introduces leverage risk. Their average entry price has risen steadily, compressing the buffer against drawdowns.
Analysts note that the “margin of safety”—comparing market value to Bitcoin holdings—has tightened to levels not seen since early bull phases. A sharp drop pushing this ratio below critical thresholds could trigger forced sales, exacerbating downside.
It’s a reminder that late-cycle buyers often face thinner cushions than early accumulators. Deep profits breed patient holders; smaller buffers can lead to quicker capitulation.
Technical Perspective: Key Levels to Watch
From a pure trading standpoint, Bitcoin remains in a broader uptrend year-to-date, but recent action feels like consolidation after parabolic gains earlier.
- Support cluster around $87,000-$88,000 has held multiple tests.
- Upside resistance sits near $95,000 initially, then the psychological $100,000 magnet.
- A clean break below recent swing lows (say $83,000-$85,000) would invalidate near-term bullish structure.
- Conversely, reclaiming and holding above $92,000 could signal resumption of momentum.
Intraday volatility remains manageable—nothing like the wild swings of past cycles. Liquidity is decent, allowing for tradable ranges without excessive slippage.
Perhaps the most interesting aspect is how mature the market feels. Year-to-date returns around 30-35% look solid in absolute terms but modest compared to prior blow-off phases. Bitcoin has even lagged some traditional assets in certain windows, hinting at evolving risk-adjusted behavior.
What Could Break the Cycle?
Looking ahead, several scenarios could disrupt this repeatable pattern:
- Prolonged ETF outflows overwhelming organic demand.
- Unexpected macro shocks tightening global liquidity faster than anticipated.
- Leveraged corporate holders facing margin pressure during drawdowns.
- Regulatory developments shifting institutional sentiment.
- Simple exhaustion—after multiple cycles, participants may anticipate rebalancing moves earlier.
Any of these could push Bitcoin toward deeper support zones, perhaps retesting $80,000 or even $75,000 in a worst-case flush.
That said, absent a major catalyst, the path of least resistance still appears higher over the medium term. Institutional infrastructure is now deeply entrenched, and adoption continues broadening.
Final Thoughts: Balanced Optimism
In my experience watching these markets, the ETF-driven cycle has brought a new level of predictability to Bitcoin’s behavior—at least in the bull phase. It’s less about retail euphoria and more about systematic flows.
Right now, the setup favors bulls betting on another 60%+ expansion over the next six months. History supports it, technicals don’t contradict it, and fundamentals remain constructive overall.
But risks are undeniably higher this time. Fading momentum, macro caution, and compressed safety margins mean any breakdown could happen faster and deeper than before.
Whether you’re positioning for the rebound or hedging against cracks, staying aware of these dynamics is crucial. Bitcoin’s journey has entered a new chapter—one where institutional mechanics often dictate the rhythm.
One thing feels certain: the next 180 days should be anything but boring.
