A recent app suddenly became popular, but what it reflects is a common anxiety in contemporary society. The official name has been changed to Demumu, aiming for global expansion, but the true reason behind its popularity goes far beyond its functionality—it touches on a hidden yet real social issue: death by loneliness.

Looking globally, living alone is becoming a trend, and this phenomenon is even more evident in the crypto space. According to 2026 data, the number of single and solo dwellers continues to grow. For crypto users scattered around the world, this issue is especially worth paying attention to. When assets are stored in wallets, exchanges, or certain DeFi protocols, what happens if an accident occurs? How can these digital assets be inherited? Who can discover and protect these assets in time? This has become an increasing concern for many crypto users.
