1. Reimagining Cash: The Digital Shift

Cash is no longer king—at least not in its physical form. In 2025, digital money has firmly embedded itself into our daily lives, thanks to the global surge in mobile payment technologies. From buying groceries to splitting bills with friends, digital wallets now replicate everything cash used to do—only faster, safer, and more integrated.
