GENIUS Act: Cancel Your Money? (Ad)

A new law called the GENIUS Act could quietly trigger the most radical shift in American finance in decades. Backed by the government but powered by private corporations, this initiative paves the way for digital dollars—programmable, trackable, and outside your control. Once embedded into apps, banks, and retail systems, opting out may no longer be possible. But there’s still time to protect your financial freedom—if you act before the system goes fully live.
