Fold, a Bitcoin-exclusive financial services application, has filed an S-4 registration statement with the US Securities and Exchange Commission (SEC), according to Bitcoin Magazine. This move signals Fold's intention to go public through an initial public offering (IPO). Fold allows users to get paid in Bitcoin, spend it on goods and services, pay bills, and more. The platform also rewards users with Bitcoin for using its Fold Card, a debit card that converts traditional fiat currency payments into Bitcoin rewards. Fold's SEC filing indicates that the company holds more than 1,000 BTC, highlighting its significant stake in the cryptocurrency. The company's decision to go public through an IPO could be a major boost for Bitcoin adoption and mainstream acceptance. By providing investors with a regulated and accessible way to invest in Bitcoin, Fold's IPO could further legitimize the cryptocurrency and attract new users.
