The assessment is "likely_true" with high confidence based on the overwhelming consistency across multiple, independent sources. A significant number of news outlets with high relevance (Decrypt, BeInCrypto, Cryptopolitan, AMBCrypto, Bitget) explicitly corroborate the claim that Long-Term Holders (LTHs) sold 815,000 BTC within a one-month or 30-day timeframe. The credibility of this claim is substantially strengthened by the fact that multiple reports (BeInCrypto, Cryptopolitan, Bitget) trace the data back to a single, authoritative primary source: the on-chain analytics firm CryptoQuant. This clear and consistent attribution to a reputable data provider suggests the figure is not speculative but is based on a specific market analysis.While one source, a social media post from CryptoQuant, presents a different figure (-104K BTC/month), this is not necessarily a direct contradiction. On-chain analysis involves various metrics. The 815,000 BTC figure likely refers to the total volume of coins *spent* by the LTH cohort, while the -104K BTC figure more likely represents the *net position change* (volume spent minus volume acquired/matured into LTH status). The statement uses the word "sold," which can align with the gross amount spent. Therefore, the two figures are likely describing different but related market dynamics.In summary, the high degree of corroboration from multiple secondary sources, all pointing to the same credible primary source, provides strong evidence for the statement's truthfulness, while the potentially conflicting data can be reasonably explained by a difference in metrics.
