South Korean engineer Shaun has big plans to develop the parcels of land he has snapped up for millions of won in recent years into long-term money-spinners.

"I'm planning to design my building which is suitable to host K-pop live performances and K-drama screenings," the 30-year-old investor said. "That can probably lead to a profitable business model in two to three years."

And construction won't be hampered by any coronavirus pandemic-spurred labor shortages or increased costs. Shaun's grand project is all in the blockchain-based virtual world Decentraland.
