Bitcoin December 2025 opened with a weak start. The market dynamics surrounding this new monthly candle are already in the spotlight, and traders are sharply observing.

Trader Daan Crypto Trades points to a recurring pattern in 2025. He shared a year-to-date setup on X, showing that Bitcoin often sets its monthly extremes early in the month. “We know by now that the first move often creates the monthly high or low within the first 12 days,” he said. “This happens about 80% of the months.” His chart shows how the February low, the March high, and the crucial levels in October and November all played out within that time frame, with June and August as notable exceptions.

So far, December has been showing a contradictory pattern. "The price has fallen rapidly from the open of the December candlestick, without any upward shadow," Daan noted. "This doesn't make it the strongest high." These kinds of immediate, one-sided moves, he argues, are often retested. He recommends keeping a close eye on the next one to two weeks: "Such immediate moves are often retested. October was a good example of this recently."

Daan's second chart focuses on key levels. After bottoming around $80.714 on November 21st, Bitcoin made a relief move of about 15% to a thicker zone of previous support, now acting as resistance, in the low $93.000s. This initial test failed, leading to a price pullback.

"BTC confirms the previous support and resistance zone," he wrote. "This isn't what you want to see as a bullish trader. The price saw a substantial 15% relief move but has lost momentum again." On the same chart, he lays out a short-term Fibonacci retracement pattern, from the local high of $93.175 to the low of $80.714. The 0.786 retracement is around $83.381, close to the current price at the time of posting.

"It's early in the week/month," he added, "and we often see sharp moves right off the new monthly candlestick. These aren't usually the strongest highs/lows set right at the start of a new month. So it's good to keep an eye on this in the coming days. (You also know I love my .786 Fibonacci retracement tests, so keep a close eye on this zone.)"

This gives a clear strategy map: immediate downward levels around the 0.786 retracement and the previous low, with conviction for an uptrend only if the price can re-enter and reclaim the mid- to high-$80.000s.

Daan places this situation within the broader historical profile of December. He shared a Coinglass chart of Bitcoin's monthly returns from 2013 to date and characterized December as "quite mixed, but [one that] had some big outliers with a lot of volatility has seen.”

The data supports this: previous Decembers ranged from large gains of over 30-40% to deep declines of over -30%. The average return in December is modestly positive (+4,75%), while the median is slightly negative (-3,22%). This underscores that there is no simple "Santa rally" effect; instead, dispersion and volatility dominate.

For Daan, some of that behavior is structural. "Don't expect any unusual movements at the end and beginning of the year," he warned. "Generally, this is a period when large holders/funds rebalance their books. We could also see the effects of tax-loss harvesting at some point." Such portfolio adjustments and tax-driven trades can amplify movements in both directions, especially in an asset that still trades with some thin liquidity areas.

His practical advice is deliberately conservative: “It's good to be allocated in a way that feels comfortable for you, regardless of what the end of 2025 and the beginning of 2026 brings.”
