The founding father of Grupo Salinas traces his skepticism of fiat forex to household dinner desk conversations about Nixon ending the gold commonplace, and views Bitcoin as superior to each money and gold as a result of it’s unseizable and borderless.
His conviction has survived a $150 million mortgage rip-off, regulatory pushback on his plans to make Banco Azteca Mexico’s first Bitcoin-accepting financial institution, and a number of market cycles.
He not too long ago pointed to a decade of London property costs as proof of his thesis — a house that price 4,000 BTC in 2016 now prices fewer than 30 — and urges strange buyers to transform their dwelling fairness into BTC publicity, calling it “an asymmetrical guess to the upside.”
