Your comment was funny to read. Thank you for that. Visa/MC are going nowhere, and no, the era is not gone, the era is actually booming even more (to your deception lol). Visa/MC are slowing also entering into the crypto and tokenization markets recently :)

These systems, like Pix for Brazil, are for nationals only (usually). Have you ever traveled in your life? Have you ever heard about the word "tourism"? Have a good day (lol).
