[Analysis: Bitcoin constrained by descending trendline resistance, short-term support lies in the $84,000 to $84,500 range] According to CoinDesk analyst Omkar Godbole, Bitcoin's price on December 23 was hindered by the descending trendline from the historical high of $126,000, failing to break through the $90,000 mark and continuing the downward pattern of the fourth quarter. Currently, Bitcoin's short-term support lies in the $84,000 to $84,500 range, and if breached, it may test the November low of $80,000. The analysis indicates that only by breaking through this trendline resistance can Bitcoin regain an upward trend, with a potential target of $100,000.
