BREAKING: SQUARE TO AUTO-ENABLE BITCOIN PAYMENTS FOR MILLIONS OF SELLERS Square will auto-enable Bitcoin payments for all eligible sellers starting March 30, 2026, according to an updated Terms of Service notice sent to users. The change means millions of businesses using Square could soon begin accepting Bitcoin by default, rather than opting in manually. The rollout is part of Block’s broader push to integrate Bitcoin payments across its ecosystem, leveraging the Lightning Network for fast, low-cost transactions. Sellers will still have the option to disable the feature or automatically convert Bitcoin to USD at the point of sale. With Square powering millions of merchants globally, this marks a major step toward making Bitcoin a standard payment method in everyday commerce.

The token cost to build a production feature is now lower than the meeting cost to discuss building that feature. Let me rephrase. It is literally cheaper to build the thing and see if it works than to have a 30 minute planning meeting about whether you should build it. It’s wild when you think about it. This completely inverts how you should run a software organization. The planning layer becomes the bottleneck because the building layer is essentially free. The cost of code has dropped to essentially 0. The rational response is to eliminate planning for anything that can be tested empirically. Don’t debate whether a feature will work. Just build it in 2 hours, measure it with a group of customers, and then decide to kill or keep it. I saw a startup operating this way and their build velocity is up 20x. Decision quality is up because every decision is informed by a real prototype, not a slide deck and an expensive meeting. We went from “move fast and break things” to “move fast and build everything.” The planning industrial complex is dead. Thank god.
