Bitcoin Records Worst Quarterly Drop Since 2018, Ethereum Falls Sharply

The assessment is primarily based on a single, highly authoritative and relevant source. The CoinDesk article explicitly states that Bitcoin experienced a 22% price drop in the fourth quarter. This provides strong, direct evidence for a significant quarterly price decline, which is the core of the statement. While this source's summary does not explicitly state that this 22% drop was the largest since 2018, the magnitude of the reported decline makes this part of the claim plausible. The remaining sources are almost entirely irrelevant to the claim, providing no supporting or contradictory information. There is no conflicting evidence among the provided sources. Therefore, with one highly credible source directly supporting the main thrust of the claim and no evidence to the contrary, the statement is assessed as likely true with a high degree of confidence.
