December 18, 2025 – Bitcoin (BTC) traders are closely monitoring the cryptocurrency’s weekly Relative Strength Index (RSI), which has dipped just below 37, inching toward oversold levels that have historically preceded significant price surges and marked major market bottoms.
As of December 18, Bitcoin trades around $86,600, reflecting a modest pullback amid thinning year-end liquidity and broader risk aversion. The flagship asset has corrected over 30% from its October all-time high above $126,000, but technical indicators suggest exhaustion in selling pressure may be near.
The weekly RSI, a key momentum oscillator ranging from 0 to 100, signals oversold conditions below 30—often interpreted as a potential undervaluation where downside momentum wanes. Current readings near 37 are the lowest since the 2022 bear market trough, when BTC bottomed around $16,500. Macro analyst Julien Bittel of Global Macro Investor highlighted historical data showing Bitcoin’s average trajectory after RSI drops below 30: in the five prior instances, substantial rebounds followed, with gains averaging triple-digit percentages in subsequent months.
Bittel argues this setup challenges the rigid four-year halving cycle narrative, pointing instead to an extended bull market potentially lasting into 2026. Supporting this, on-chain metrics reveal steady institutional accumulation, with spot ETF inflows remaining resilient despite price dips. Corporate treasuries, led by firms like MicroStrategy, continue adding BTC, viewing current levels as attractive entry points.
Daily and shorter-term RSIs also flirt with oversold zones, with the 14-day indicator hovering in the low 40s—neutral but showing divergence where prices decline while momentum stabilizes. Hidden bullish patterns on higher timeframes, combined with support holding near $85,000-$86,000, bolster cases for a relief rally. A decisive break above $90,000 could target $95,000-$100,000 swiftly, fueled by short squeezes and renewed FOMO.
Critics caution that oversold readings alone do not guarantee reversals, especially if macroeconomic headwinds—like delayed rate cuts or geopolitical tensions—persist. However, the confluence of historical precedents, improving global liquidity projections, and Bitcoin’s dominance climbing toward 60% paints an optimistic longer-term picture.
This RSI development arrives as the crypto sector matures, with regulatory tailwinds and tokenized asset adoption accelerating. Analysts widely view sub-30 weekly RSI breaches as rare “buy the dip” opportunities, occurring only at cycle inflection points.
As 2025 winds down, Bitcoin’s path forward hinges on whether this oversold signal ignites the next leg up, potentially setting the stage for fresh highs in the new year.
