According to @AltcoinDaily, Bitcoin BTC reached 90,000 USD on Jan 2, 2026, signaling a test of a major round-number threshold that traders monitor closely for momentum shifts (source: @AltcoinDaily on X, Jan 2, 2026). Round-number levels such as 90,000 USD often behave as psychological resistance or support due to price clustering, concentrating orders and increasing whipsaw risk near the level (source: CFA Institute, materials on price clustering and round-number effects). For confirmation, many technicians look for a daily close and follow-through above the breakout level or a higher-high and higher-low structure before treating the move as sustained, guiding entries and risk placement (source: CMT Association, Technical Analysis Body of Knowledge). Volatility typically rises around clustered options strikes and key thresholds, so monitoring BTC options activity and liquidity near the 90,000 strike can help gauge potential gamma effects and liquidity gaps (source: CME Group, options education on strike clustering and gamma dynamics).

According to @glassnode, options markets can dampen or reinforce price moves via dealer hedging flows (source: Glassnode post on X dated Dec 19, 2025; source: glassno.de/49kqje4). According to @glassnode, the new Gamma Exposure GEX metric maps where options market structure is likely to stabilize price or amplify volatility (source: Glassnode post on X dated Dec 19, 2025; source: glassno.de/49kqje4). According to @glassnode, monitoring GEX can help traders identify stabilization versus amplification zones and align hedges, position sizing, and stop placement with the prevailing options-driven volatility regime (source: Glassnode post on X dated Dec 19, 2025; source: glassno.de/49kqje4).

According to the source, BTC is down 6% month-to-date in October with 12 days remaining, putting a premium on flow- and positioning-confirmation over directional guesses for the rest of the month (source: public X post dated Oct 18, 2025). Monitor net spot Bitcoin ETF inflows/outflows each US session; sustained net inflows tend to support intraday bid and reduce drawdown persistence, while net outflows often coincide with weaker price action (source: Farside Investors US spot Bitcoin ETF flow tracker; source: Bloomberg ETF flow summaries). Track perpetual funding rates and basis alongside open interest; persistent negative funding with rising open interest indicates aggressive short buildup and raises short-squeeze risk if flows flip, favoring fade-the-break tactics near obvious lows (source: Coinalyze funding and open interest data; source: Glassnode futures and derivatives metrics). Watch options open interest concentration at round-number strikes into weekly and month-end expiries; heavy call gamma above spot can cap rallies, while put gamma clusters below spot can accelerate selloffs if breached (source: Deribit options OI and expiries; source: Laevitas options gamma analytics). Frame risk using the 100–200 day moving averages and the monthly open/close as dynamic support/resistance; violations often precede liquidity grabs before mean reversion in range-bound environments (source: TradingView BTCUSD moving averages; source: CMT Association technical analysis references).
