Bank of America: 'Digital Dollar Inevitable' (Ad)

Bank of America just revealed your expiration date. In their Bloomberg interview, they didn't just predict the digital dollar. They gave us the timeline… 2025 to 2030. We're in that window right now. Once the digital dollar launches, every transaction you make will be tracked. Your spending could be controlled. Your accounts could be frozen. Over 4,500 investors have already used this legal backdoor to hold assets CBDCs can't freeze and generate yields the Federal Reserve can't touch.tc pixel

Watch how to access the legal backdoor before it closes.
