The assessment is primarily based on the convergence of evidence from highly relevant and authoritative sources. The summary for the CryptoQuant insights page indicates it is a primary source from a respected on-chain analytics platform discussing the exact metric in the statement (BTC inflows to Binance). This provides strong, direct support for the claim. The Cointelegraph news article further corroborates this by discussing the analysis of average transaction sizes and the impact of "whale" movements, which explains how an average could reach such a high figure; a few very large transactions can significantly skew the monthly average. The potentially conflicting data from the MEXC article, which states the average fell to 0.57 BTC in September, does not fundamentally contradict the claim. The statement says the average "reached" 29.7 BTC, implying a peak or a specific month's value, not a constant figure. It is plausible for a volatile metric like this to be 0.57 BTC in one month and 29.7 BTC in another, especially one influenced by large, infrequent whale deposits. Other sources were either irrelevant (total exchange volume, casino guide) or provided weak contextual support (a single large transaction), but none offered a direct refutation of the claim. Therefore, with a primary data source and strong contextual evidence, the statement is assessed as likely true with high confidence.
