Bitcoin Is Math Long Sleeve T-Shirt
Numbers don't lie, and neither does Bitcoin. This long sleeve breaks down the mathematical proof behind Bitcoin's 21 million cap – because when people ask "but how do you know there will only be 21 million?", you can literally point to your shirt.
Perfect for devs who speak in code, economists who get excited about fixed supply schedules, and anyone who'd rather trust math than some suit at the Fed. Rock this to your next meetup and watch the conversations flow from halving cycles to hash rates.
Makes an excellent gift for the number-crunching Bitcoiner in your life – especially one heading to Bitcoin 2026 who wants to wear their convictions. Available in sizes S-4XL with free shipping on all U.S. orders.
Long sleeves for long-term thinking. Mathematical certainty never looked so good.
