Data highlights that Bitcoin has experienced significant declines, marking a struggling end to the year. Bitcoin fell approximately 3.7% in October and 17.7% (specifically -17.87%) in November. This downward trend persisted into the start of December, raising concerns among traders. Market observers note that the last time Bitcoin recorded a fully red fourth quarter—with negative returns in October, November, and December—was during the 2018 bear market cycle. The current price action is drawing uncomfortable parallels to that period, suggesting potential further weakness if December does not reverse the trend. [Update 1] Recent market data confirms that November's close has shifted Bitcoin's year-to-date (YTD) performance into negative territory. The asset's price has dropped from a yearly open of $93,347 to around $90,369. This marks the third consecutive month of negative returns, a sustained drawdown pattern last observed in 2022.
