The dollar just broke (Ad)

Bloomberg research shows the U.S. dollar's share of global reserves has fallen to the lowest level this century — and the consequences for your savings and investments could be severe. President Trump has signed executive order 14241 to initiate the first full reset of the American dollar in 50 years. A new monetary anchor is being established — one that's not gold or crypto, but something far more unexpected that Vladimir Putin once called the key to world leadership.tc pixel

The Pentagon is desperate (Ad)

The Pentagon has admitted the US trails Russia and China in hypersonic weapons, and its research budget has nearly tripled in five years. One small Florida company, trading under $5, is already under contract with Lockheed Martin, GE Aerospace, and the US Air Force to help test this technology at extreme altitudes. The company also launches commercial satellites and is nearing a major licensing milestone that could reshape its valuation.tc pixel
