Experts say bitcoin may be viewed as a long-term investment but should take only a small share of retirement assets because volatility and the risk of losses at withdrawal matter most. Industry sentiment is leaning toward limited allocations rather than making bitcoin a core holding. Some firms suggest 1 to 2 percent or 2 to 5 percent, while advisers recommend keeping crypto below 5 percent. Institutions also tend to invest indirectly via regulated spot ETFs or crypto-related companies.

The Ministry of Science and ICT’s Postal Service said it launched the \'Post Office My All Day Debit Card\' on Aug. 18, reflecting key spending patterns of middle-aged customers. The card offers 5 percent cashback in areas such as dining, health, exercise, culture, leisure, travel and shopping, and 10 percent cashback on postal services including postage, EMS and Post Office Shopping. Cashback benefits can total up to 30,000 won a month depending on transaction performance.
