The assessment is based on a strong consensus across multiple high-authority sources. Three independent and relevant news outlets (DL News, Yahoo Finance, and Decrypt) directly report that Coinbase has made its USDC rewards program exclusive to paid subscribers. The most compelling piece of evidence is the Yahoo Finance article, which explicitly cites a Coinbase spokesperson confirming the policy change, lending it significant credibility. This reporting is further corroborated by user-generated content on Reddit, where multiple users discuss the new requirement of a paid Coinbase One membership to earn USDC rewards. While the official Coinbase pages provided in the sources confirm the existence of the Coinbase One subscription, they are not relevant enough to either support or deny the specific claim about deposit rewards. Crucially, there is no conflicting evidence among the provided sources. The consistency and high quality of the primary news sources make it highly probable that the statement is true.
