Bitcoin's market performance during the Christmas period over the past several years has been as follows:

- 2022: Decrease of 2.7%
- 2021: Decrease of 11.9%
- 2020: Increase of 22.3%
- 2019: Decrease of 1.1%
- 2018: Decrease of 5.3%
- 2017: Increase of 4.1%

Since 2017, over the seven days following Christmas, the probability of a price decrease has been over 66%. This trend indicates a prevalent likelihood of a decline in Bitcoin's value during this particular period. It's noticeable that the market sentiment during Christmas for Bitcoin hasn't exhibited consistent bullish behavior, as evidenced by the majority of the years showing a decline in value or a relatively modest increase.

However, past performance is not indicative of future results, and various factors can influence Bitcoin's price movement beyond historical patterns.
