The Altcoin That Could be Poised to Benefit Most from Trump’s Return (Ad)

With Trump back in office, the crypto tide is turning fast. Regulation is easing. Momentum is building. And according to Weiss Ratings analyst Juan Villaverde, a major shift is coming. Juan has nailed every major Bitcoin move since 2012—but right now, he says the biggest upside isn’t in BTC or ETH. It’s in a lesser-known altcoin he believes could become the “third pillar of crypto”… and potentially define America’s first true crypto presidency.

See why Washington insiders are quietly buying this coin before it goes public.
