A 70-year-old resident in Shanghai's Chongming district was recently stopped from transferring 100,000 yuan after being misled by an online "investment mentor" promising high returns from Bitcoin investments. The individual attempted to withdraw the cash twice before being successfully dissuaded by coordinated efforts between police and bank staff. Authorities warn that scams targeting the elderly, often disguised as "Bitcoin investments" or "retirement financial plans," are on the rise. Fraudsters typically pose as financial experts on short video platforms, using fake profit screenshots and promises of "low investment, high returns, and guaranteed profits" to lure victims. Police advise verifying large financial transactions with family and reporting suspicious activities promptly.
