"Square has turned on Bitcoin payments by default for eligible US businesses. Sellers did not have to raise a hand, fill out a form, or sit through a webinar. The feature costs merchants 0% in processing fees through December 31. After that, a flat 1% fee kicks in. Square, the payments platform owned by Block, Inc., began auto-enabling Bitcoin acceptance on March 30, 2026. The full rollout across eligible sellers is scheduled to be complete by November 10, 2026."
