How far has the conference swag gone? It used to be canvas bags with logos, uniform notebooks, and now it’s directly replaced with real gold and silver—5 USDT. Not just airdrops, but instant withdrawals to accounts, which can be exchanged for local currency on the street to buy snacks or browse markets—who can resist this kind of experience?

On October 1st, a conference on blockchain technology and digital financial applications was held in Da Nang, Vietnam. Attendees only needed to register on a designated payment app to receive 5 USDT. The key is the subsequent operation: these USDT can be directly exchanged for Vietnamese dong within the regulatory sandbox area of Da Nang for consumption. Using crypto assets to buy spring rolls, drink fresh coconut—this kind of "on-chain assets turning into offline fireworks" experience is much more stimulating than watching K-line charts.

This is not just a promotional stunt. The underlying logic is worth pondering—the regulatory sandbox is the core. Simply put, it’s about drawing a "safety circle" around limited areas and limited groups for crypto innovation, allowing testing of whether new businesses can truly land without letting risks spread. Vietnam’s choice of Da Nang as a pilot is definitely not a temporary decision.

From a technical perspective, the significance of this attempt lies in transforming crypto assets from purely virtual concepts into practically usable payment tools. The combination of student groups, real consumption scenarios, and policy support creates a framework—only then can the feasibility of blockchain technology in financial applications be truly tested. It’s not hype; it’s real-world validation. Having been immersed in the industry for years, watching crypto gradually shift from pure speculation to practical scenarios, this is where the long-term value truly lies.
