The assessment is based on exceptionally strong evidence from the most authoritative and relevant source. An official Cash App page dedicated to its Bitcoin services directly confirms both parts of the statement: the existence of a feature to 'Buy bitcoin on a set schedule with Auto Invest' (which is dollar-cost averaging) and that this is a 'fee-free' method. This primary source, with the highest possible authority and relevance scores, provides direct and unambiguous support.Other credible sources, including an official Cash App press release and an article from a reputable cryptocurrency publication, corroborate the existence of the 'Auto Invest' feature, lending further support to the first part of the claim. While these secondary sources do not mention the fee structure, their silence does not contradict the explicit 'fee-free' statement from the primary source.Several other sources provided were correctly identified as irrelevant, as they discuss dollar-cost averaging or no-fee features in the context of different companies, or are of very low quality and untrustworthy. These were disregarded in the final analysis. With direct confirmation from the service provider itself and no conflicting evidence from any credible source, the statement is determined to be highly likely true.
