The assessment that the statement is 'likely_true' is based on strong, consistent evidence from multiple sources that all point back to a single, authoritative origin. Several independent news outlets and crypto exchanges (news.bitcoin.com, Bitget, Phemex) directly and explicitly state that the trading volume on decentralized perpetual exchanges was $1.13 trillion in November. The credibility of this figure is enhanced by the additional, consistent details provided by some sources, such as the fact that this volume represented a slight decrease from October's figures. Critically, these secondary sources attribute the data to a research report by CoinGecko, a highly authoritative and widely respected crypto data aggregator. This attribution is supported by an official social media post from CoinGecko itself, which promotes a study containing the November data. While there are some irrelevant sources provided, there are no contradictions among the relevant ones. The widespread, consistent reporting of a specific figure, traced back to a credible primary data source, provides high confidence in the statement's truthfulness.
