The Coin That Could Define Trump’s Crypto Presidency (Ad)

When Trump returned to office, one of his first moves was to tap PayPal’s former COO, David Sacks, as a top advisor on crypto and AI. That alone signaled a shift. But insiders close to D.C. aren’t just talking crypto policy—they’re quietly buying something most retail investors have missed. While the crowd chases Bitcoin to $150,000, Weiss Ratings expert Juan Villaverde believes a different coin—already backed by giants like Google, Visa, and PayPal—could soon become crypto’s “Third Giant.”

Discover the coin that could define Trump’s crypto presidency.
