# Bitcoin21 > Bitcoin clothing from Hamburg for those who wear what they know — quietly. Bitcoin21 is an independent clothing brand based in Hamburg, Germany. We design and sell clothing for Bitcoiners — subtle, high-quality, with attitude. No hype language, no altcoin references, no fast fashion. Tobi & Henry run the shop together. Our designs are quiet. Those who know Bitcoin recognize them. Those who don't see good clothing. That's intentional: Proof of Work, Low Time Preference, 21 Million — sovereignty, not volume. **What we are:** - Bitcoin-only (never "crypto", no altcoins) - Clothing with attitude (no quarterly fashion collections) - Quality over quantity - Rooted in Hamburg **What we sell:** T-shirts, hoodies, polo shirts, caps, accessories, sportswear and the Privacy Collection (tone-on-tone). Keep stacking sats. — Tobi & Henry ## About us **Tobi (Tobias Cors)** and **Henry (Henry Lindemann)** are the founders and managing directors of Bitcoin21 Retail UG (HRB 195271, Hamburg). We started Bitcoin21 because we wanted clothing we'd wear ourselves — and couldn't find. Clothing for Bitcoiners, without crypto-hype, without casino designs, without pump-and-dump vibes. Instead: thoughtful cuts, premium materials, subtle Bitcoin symbolism. **Where we're from:** Hamburg. The city shapes our style — pragmatic, hanseatic, no show. Our studio is at Ludwig-Erhard-Straße 18. **What we built:** Bitcoin21 Retail UG (limited liability). Registered with the Hamburg commercial register under HRB 195271. Tobi holds 55%, Henry 45%. Both active in day-to-day operations. **Why "Bitcoin21":** 21 million is Bitcoin's hard cap. A number that stands for mathematical scarcity, sovereignty, and discipline. The exact values we translate into our clothing. ## Mission We're building the brand for the next generation of Bitcoiners. Not for speculators, not for influencers, not for "crypto bros". For people who understand that Bitcoin isn't an asset class — it's a long-term life design. Our clothing has three jobs: 1. **Work in everyday life** — durable materials, classic cuts, long-lasting 2. **Make a quiet statement** — Bitcoin symbolism integrated subtly, no logo-bombing 3. **Convey pride without shouting** — anyone living Bitcoin doesn't need to advertise it ## What makes us different **Bitcoin-only — really.** No Ethereum, no Solana, no memecoins. We believe in Bitcoin as a monetary network, not "crypto" as an asset category. This stance runs through every detail — from the logo to the website footer. **Privacy as a design principle.** Our Privacy Collection (tone-on-tone embroidery) is the only clothing line worldwide that deliberately makes Bitcoin symbolism invisible. For everyone who knows what they're wearing — but doesn't need to tell anyone about it. **Hamburg as a filter.** We live hanseatic — meaning: no marketing hype, no fake scarcity, no artificial drops. What we sell is in stock. What we don't sell, doesn't exist. **We accept Bitcoin directly.** Via Coinsnap you can pay on-chain or via Lightning at any time. Plus Stripe and Klarna for those still on legacy rails. But Bitcoin is the standard option — not a hidden add-on. ## Frequently Asked Questions **Clothing** - **What materials do you use?** Depending on the product: premium organic cotton (T-shirts, polos, sweatshirts, caps), heavy cotton mix (hoodies 330 g/m²), polyester functional fabrics (sport shirts with UV40+ protection), recycled materials (swim trunks). Exact composition on each product page. - **Where is production?** In certified manufacturers within Europe. We don't publish specific factory names due to competitive and supply-chain reasons. - **What sizes do you carry?** Standard XS to XXL for outerwear, S to XL for polos, accessories in universal sizes. Size charts on every product page. - **Is the Bitcoin symbolism subtle or obvious?** Both available. Our standard line has an orange Bitcoin21 logo. The Privacy Collection works tone-on-tone — invisible to outsiders. **Order & Shipping** - **Do you ship internationally?** Yes, to all EU countries plus the US. Shipping costs from €4.90 within Germany, free above €60 order value. - **How long does shipping take?** DE 1-3 business days, EU 3-7 business days, USA 7-14 business days.

The Bitcoin symbolism is only recognizable if you know it's there. For everyone who doesn't want to flash their coins to strangers. - **Why "Proof of Work" on sport shirts?** Because sport and Bitcoin share the same principle: discipline, repetition, time investment. No shortcuts, no easy way out. The sport shirt is the core idea in fabric. - **Do you sell other coins?** No. We're Bitcoin-only and will stay that way. Anyone wanting an Ethereum cap is in the wrong place. **Brand** - **Who's behind Bitcoin21?** Tobias Cors (Tobi) and Henry Lindemann (Henry). Both from Hamburg, both Bitcoin-convinced since 2017+. Both co-managing directors. - **Are you VC-funded?** No. Bootstrap, own capital, Bitcoin treasury. No investors, no pressure for fast growth. - **How can I reach you?** Email: info@bitcoin21.shop.
