A Taipei Metro incident that initially drew online suspicion over possible espionage was later determined by police to be an online investment course viewed by a 48-year-old man on a station platform. The screen reportedly showed phrases such as “Zone 2 Photosynthesis System,” while the course content included “compound interest.” After the national security angle fell away, the focus shifted to what kind of investment program uses terms like “battle zones” and “photosynthesis system.” Manhsiu Hsu, founder of blockchain media outlet Blocktrend, traced those keywords and found a strong overlap with public promotional material tied to CaryPact, a crypto investment project built around BOT Chain. Public guides for CaryPact describe a model in which participants buy “AI computing power servers,” convert CA tokens into a BOT Chain-based token labeled USDT, and bridge assets to BNB Chain. Hsu’s review also found references in CaryPact communities to “zones,” “photosynthesis system,” and even a course titled “Network Plan and Compound Interest ×3.” There is still no direct evidence that the man in the MRT incident was a CaryPact investor or member, and there has been no judicial finding sufficient to label CaryPact a scam. Still, the overlap in public materials has shifted scrutiny from espionage fears to questions about investment risk, token identity, and whether the project’s returns can be independently verified through real operating data.
