# Bitcoin21 > Bitcoin clothing for people who know what they wear. Bitcoin21 is an independent clothing brand based in Hamburg, Germany. Design, embroidery and printing take place there — for every product in the range, without exception. We design and sell clothing for Bitcoiners — subtle, high-quality, made to be worn. No hype language, no altcoin references, no fast fashion. Tobi & Henry run the shop together. Our designs are discreet. 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 a big logo. **What we are:** - Bitcoin-only (never "crypto", no altcoins) - Clothing that lasts (no new range every quarter) - Quality over quantity - Rooted in Hamburg **What we sell:** T-shirts, hoodies, polo shirts, caps, accessories, sportswear and the Privacy pieces (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. **Wear Bitcoin discreetly** — Bitcoin symbolism integrated with restraint, no logo-bombing 3. **Convey pride without pushing** — anyone living Bitcoin doesn't need to convince anyone ## 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.** On the Privacy pieces the Bitcoin21 logo is embroidered tone-on-tone, in the colour of the fabric. Just as much Bitcoin, only less visible — you decide how obvious you wear 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.** You can pay on-chain or over Lightning, right in the checkout and straight from your own wallet. Card, Klarna and the usual wallets are there too — but Bitcoin is not a footnote here, it is an ordinary payment method. ## 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?** Printing and embroidery take place in Hamburg; the textile blanks are sourced internationally from selected producers. We don't publish specific factory names due to competitive and supply-chain reasons. - **What sizes do you carry?** Most tops in S to XL, many T-shirts also in XS. Up to XXL: Worker Jacket, Sherpa jacket, both WeWill+ shirts, running shirt and swim shorts. Socks in 35–38, 39–42, 43–46 and 47–50, caps one size. Size charts on the product pages. - **Is the Bitcoin symbolism subtle or obvious?** Both available. Our standard pieces carry the Bitcoin21 logo in orange. On the Privacy pieces it is embroidered tone-on-tone, in the colour of the fabric — just as much Bitcoin, only less visible. **Order & Shipping** - **Do you ship internationally?** Currently to Germany, the entire EU and Switzerland. Flat shipping €4.99, free above €75 order value. For deliveries to Switzerland, customs duties and import taxes of the destination country may apply. - **How long does shipping take?** We usually ship the next business day, no matter the destination. From order to delivery it normally takes 1–3 business days within Germany, 3–6 business days within the EU and 5–10 business days to Switzerland. Shipped via DHL. These are guide values, not guaranteed times. - **Which payment methods?** Bitcoin on-chain and over Lightning, right in the checkout. Plus credit and debit card (Visa, Mastercard, American Express, Maestro), Klarna, Apple Pay, Google Pay, Shop Pay and, depending on the country, local methods such as Twint, Bancontact, BLIK or Przelewy24. - **Can I return items?** Yes, 14 days right of withdrawal without giving a reason. Trying items on is explicitly fine; only a loss in value beyond that may be offset. The buyer bears the direct cost of return shipping (except for defective or incorrect items). **Bitcoin-Specific** - **What are the Privacy pieces?** Clothing with tone-on-tone embroidery instead of an orange logo. Just as much Bitcoin, only less visible. 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. Address: Bitcoin21 Retail UG, Ludwig-Erhard-Str. 18, 20459 Hamburg. ## How we work - **Bitcoin-only.** No Ethereum, no Solana, no memecoins. Bitcoin as a monetary network, not "crypto" as an asset category. - **Understated design.** A small logo instead of a large print.
