The statement's truthfulness is strongly supported by a consensus across multiple high-authority sources. The primary sources, which are a blog post and a product page directly from the company Lemon, are the most compelling evidence. The official announcement explicitly states the launch of a Visa credit card 'respaldada en Bitcoin' (backed by Bitcoin). This is directly and consistently corroborated by several secondary news sources (Crowdfund Insider, AInvest, HokaNews), which all report on the launch of a 'Bitcoin-Backed Visa Credit Card' by the 'Argentinian' company 'Lemon'. There are no contradictions among the sources. While one help center article does not detail the collateralization aspect, its purpose is more general, and its omission does not contradict the explicit statements made in the official launch announcements. The combined weight and consistency of the evidence, particularly the direct confirmation from the company itself, make the statement highly likely to be true.
