Bitcoin at an Inflection After a Record Options Expiry: 85K and 90.1K Breakout Watch, Binance USD1 Issue, and MSTR Indicator Check

Key Takeaways

With options expiry out of the way, Bitcoin is seeking direction at the critical inflection zone between 85K and 90.1K. We caution against expanding short‑term leverage and suggest waiting for a clear recovery in volume and confirmed breakouts before entering. Meanwhile, the sharp drop on Binance’s USD1 pair and a decline in MicroStrategy (MSTR) indicators are highlighted as short‑term risk factors.

Options Expiry and Volatility Drivers

The notional size of this month’s options expiry was introduced as approximately KRW 4.5 trillion. Ahead of and just after expiry, position‑trimming pressures that had been pushing price both ways have eased. We note that below 85K and above 90.1K were dealer loss zones; therefore, post‑expiry breakouts through these levels could signal a trend shift. While perpetual futures are less sensitive to expiry, options require periodic closing and re‑establishment, making volatility more likely around settlement.

Chart View: Support/Resistance and Trading Ideas

We are watching for a rebound near the Point of Control (POC) around 87K and whether price can reclaim 89.5K in the near term. On the topside, 90.1K aligns with Bat (harmonic) pattern resistance and a historical supply zone; a clean breakout could open room toward 92K–93K. Conversely, losing support at 85.1K could deepen the downside, and a brief dip below 80K followed by a retrace remains on the table. Although price has pierced the upper boundary of a descending channel, confirmation is still needed. We recommend a conservative approach: define invalidation levels in advance and enter after signals confirm. Prioritize reactions at confluence zones where S/R flips, Fibonacci retracements, and channel boundaries overlap.

Binance USD1 Pair Flash Drop Incident

Confirmed data show an abnormal wick on Binance’s BTC/USD1 spot pair around Christmas, plunging to roughly 24,111 before snapping back. There was a prior announcement of 20% APY on USD1 staking; liquidity being locked in staking may have thinned the order book, creating an opening for a cascade of market sells followed by arbitrage bot buying. We do not assert intentional intervention but acknowledge the suspicion that has been raised. As a risk‑management practice, avoid newly listed or illiquid pairs where possible, or place far‑off limit orders with very small size. This appears to be confined to a specific pair and should not be read as a signal of systemic market collapse.

On‑Chain and Derivatives Metrics: Softening Demand and Leverage Risks

Our read of the data suggests exchange balances are rising and withdrawals have stalled, indicating weak spot demand, while deposits have ticked up slightly. Open interest has cooled, but estimated leverage ratios are climbing; since October, similar phases of rising leverage have often coincided with price pullbacks. Volumes in both spot and derivatives have compressed to near weekend levels, making it hard to argue for structural improvement. The Coinbase premium is soft, and we observe a bearish divergence characterized by rising price lows against falling demand lows. That said, adjusted Coin Days Destroyed shows limited signs of meaningful long‑term holder distribution, implying the mid‑cycle accumulation phase remains intact.

MicroStrategy (MSTR) Indicator Deterioration and January Variables

MSTR’s market‑cap‑to‑BTC‑holdings value ratio (often referred to as MNAV) has slipped to about 1.06, down quickly from roughly 1.15 two weeks ago. A sustained move below 1 could, in theory, increase the risk of BTC selling pressure, though MSTR can also defend the metric via buybacks funded with cash on hand. We estimate MSTR’s average BTC acquisition cost at approximately 74,000. Monitor potential MSCI‑related exclusion risk around January 15. From a price‑level perspective, we view the 152, 133, and 100 areas as key supports and advocate a conservative stance with clear invalidation in the event of further downside. This section reflects our interpretation and should not be conflated with corporate decision‑making or any forced‑sale requirements.

Crypto‑Related Equities: Coinbase, “Bitmain,” Marathon

For Coinbase (COIN), we are watching for a potential rebound near the 0.786 retracement where it coincides with the lower channel around 210, with secondary defense around 175. For the mining/infrastructure name referred to as “Bitmain,” we consider the 20 area as the first accumulation zone and 15 as a secondary zone. Marathon Holdings appears to have turned lower and completed a retest, warranting caution and selective engagement. These price zones reflect a technical view and require strict risk management irrespective of the companies’ fundamentals.

Ethereum: Box Top Breakout vs. Bottom Breach

If Ethereum clears the 3,020–3,040 band, we see scope for the short‑term uptrend to continue with a test of the 3,200 area. On the downside, 2,840–2,830 is highlighted as key support where a Gartley pattern overlaps with supply; a breakdown could open a strong spot‑buying candidate zone in the 2,400–2,300s. We are considering a scaled accumulation in that lower range with a medium‑ to long‑term holding horizon; treat this as our plan, and distinguish between facts and forward‑looking views.

Seasonality Watch: Statistical Room for a Santa Rally

Regarding the S&P 500’s Santa Rally window (the five trading days around the turn of the year), we note that since 1928 there have been no instances of three consecutive yearly declines in that period. This could be a supportive backdrop for risk sentiment early in the year, though equity seasonality does not guarantee immediate upside in Bitcoin.

Investor Checkpoints and Conclusion

The current market calls for caution in the short term amid thinning volumes, a weak Coinbase premium, and rising leverage. We favor a trend‑following approach only after confirmed breakouts centered on 85K and 90.1K, with clear invalidation and avoidance of excessive leverage. Keep in mind that issues similar to Binance’s USD1 illiquid‑pair event can recur; maintain balance by not over‑extrapolating isolated incidents into broad market risk. With the mid‑cycle accumulation interpretation still viable, it appears prudent to monitor the key zones calmly and adjust cash, spot, and derivatives exposure with flexibility.
