加密货币市场下跌4.4%，比特币跌超5%

The assessment is based on strong, corroborating evidence from multiple high-authority sources. Two of the most credible sources, CoinMarketCap (Authority: 0.95) and Binance (Authority: 0.90), directly confirm that the total crypto market capitalization fell by 4.4%. The Binance source further references a 5% figure in the context of the selloff, which strongly supports the second part of the statement regarding Bitcoin's decline.A third relevant source from the Phemex exchange (Authority: 0.65) also confirms a major market selloff led by Bitcoin. While it reports a slightly different market cap decline (5.51%), it reinforces the core claim that the market fell significantly and that Bitcoin's losses were a primary driver, making it plausible that BTC's individual decline was greater than the market average. This minor numerical discrepancy is common between different data aggregators due to slight variations in timing and methodology, and does not undermine the overall veracity of the statement.Conversely, the sources that present contradictory or irrelevant information are of significantly lower authority (e.g., Facebook posts, individual user analysis on TradingView) or are clearly discussing a different market event. There is no credible, high-authority evidence to refute the statement. The convergence of data from top-tier industry sources makes the statement highly likely to be true.
