The statement is strongly supported by an overwhelming consensus among the provided high-authority sources. Both key claims—the total weekly outflow of $782 million and the specific $276 million outflow on a Friday—are explicitly confirmed by multiple credible outlets, including Cointelegraph, Whale Alert, Binance, and CoinMarketCap.The first claim, a $782 million total weekly outflow, is consistently reported across nearly all relevant sources with no contradictions.The second claim, a $276 million outflow on a Friday, is also corroborated by a majority of the high-authority sources. There is one piece of conflicting evidence from Wu Blockchain, a source with high authority, which reports the same $276 million outflow but attributes it to December 26, which contradicts the 'Friday' detail. However, this is a single outlier report when compared to the consistent narrative presented by four other high-authority sources. Given the strong, multi-source agreement on both figures and the day of the week, the statement is assessed as highly credible. The single contradictory data point is noted but is insufficient to outweigh the substantial body of corroborating evidence.
