Fold’s no-annual-fee metal Visa credit card went live March 17 via Stripe and Celtic Bank.

The card makes Fold the first publicly traded company (NASDAQ: FLD) to offer a bitcoin-only credit card.

Market Context: The $607M monthly record confirms that crypto cards are now a meaningful payment vertical, not an experiment. The KAST Season 6 rate cuts — while expected — signal that early-adopter subsidy-era rewards are winding down as providers move toward sustainability. Fold’s bitcoin credit card is a bet that BTC-only rewards can compete in a market dominated by multi-token programs.
