Bitfinex Securities said it would refund its investors in the El Salvador International Airport Hilton project after failing to attract the minimum $500,000 needed to continue operations. The project was El Salvador's initial public offering of digital debt assets, but only raised $342,000 from investors before the first deadline, just 5% of the $6.25 million it hoped to raise. The funds are designed to fund the construction of the Hilton Hampton Inn, a 4,500-square-foot hotel divided into five floors with 80 rooms, a restaurant, work area, swimming pool, gym, and gardens.
