Block Enables Bitcoin For Merchants According to company notices and trade reporting, merchants can accept Bitcoin payments directly at the point of sale, with transactions able to settle over the Lightning Network to speed up confirmation times. The feature also includes automatic conversion options so sellers can choose to receive fiat or hold BTC. our sellers can now receive btc to btc, btc to fiat, fiat to btc, or fiat to fiat. https://t.co/NnLsd3fgEb -- jack (@jack) November 10, 2025 Fees And Conversion Rules Based on reports, Block will not charge processing fees for Bitcoin payments through January 1, 2027; after that date a fee of roughly 1% per transaction is expected to apply. Some pieces also say merchants may be allowed to convert up to 50% of daily card sales into Bitcoin automatically, giving businesses an easy way to build a crypto position from routine revenue. The current rollout is focused on the US market, with certain regions such as New York excluded for now. Adoption at scale is the key test. Getting a payment method into the Point of Sale does not guarantee customers will use it. Reports point out that many of the 4 million merchants are active sellers on Square, but uptake will depend on consumer demand, merchant settings, and how easy the checkout flow feels to shoppers. Early coverage notes that Block is highlighting the lack of chargebacks and the lower friction of Lightning to persuade smaller stores to try Bitcoin. Technical and regulatory issues were also called out. Some outlets mention limitations tied to local rules, the need for anti-money-laundering checks, and the strength of Lightning routing for small payments. Accounting and tax treatment remain practical concerns for merchants weighing whether to keep Bitcoin or convert to fiat immediately. Block has said it will integrate conversion tools to help with volatility management.

If even a fraction of the 4 million sellers enable Bitcoin, the network will see more real-world payment use. Still, adoption will likely be gradual, and results will be visible only after merchants run the feature for a few months. Featured image from Unsplash, chart from TradingView
