“All Bitcoin does is permit fraudsters to maneuver cash round,” he stated.

Gold, he added, has delivered strong features over the identical interval.
Maybe Grantham is correct, the selloff has been extreme. BTC hit an all-time excessive close to $126,000 in October 2025. Since then, the digital asset has shed greater than 50% of its worth.

U.S. spot BTC ETFs posted 4 consecutive days of web outflows totaling round $113.8 million.
Bitcoin’s try to reclaim larger floor ran straight into its 200-day transferring common, which served as onerous resistance and triggered a roughly 30% decline from that ceiling. The present drawdown is among the many fifth worst in Bitcoin’s historical past — territory that assessments the resolve of long-term holders. Some institutional consumers, nevertheless, are treating the dip as an entry level, with Coinbase reporting that main establishments have stepped in to purchase the crash.

On the flip aspect, Mexican billionaire Ricardo Salinas Pliego has positioned 70% of his funding portfolio into BTC — up from simply 10% in 2020 — and has even satisfied his spouse to mortgage their residence to purchase extra.
The founding father of Grupo Salinas traces his skepticism of fiat foreign money 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 lately 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 bizarre buyers to transform their residence fairness into BTC publicity, calling it “an asymmetrical guess to the upside.”
