How can I stay safe when buying bitcoin face-to-face? Every visitor to Buy Bitcoin Worldwide should consult a professional financial advisor before engaging in such practices. Hi Steven, Thank you for reaching out to Finder. Bitcoin ATMs are private, but there are some downsides. Its not always a case of wanting to remain anonymous, my own personal situation is that I do not have a passport, photo driving licence or government issued ID card. I only recommend Bisq for more advanced users. You can usually only buy a small amount of crypto before being asked to provide ID.
