Guides are being published on how to buy Ooki, a cryptocurrency, using various payment methods, including debit cards and specific services like Zip Pay and Mastercard. The guides appear to offer step-by-step instructions and information on features, fees, and checklists for the buying process. However, there is some inconsistency in the information, with one outlet also providing a guide on buying "Disco" with a debit card, which may or may not be related to Ooki.
