Germany is the third-largest economy in the world and the largest Bitcoin-adoption market in continental Europe (~5M holders, regulated BaFin custody licensing, active institutional ETF participation since 2024). The .de TLD signals "this is for the German market" — non-negotiable for any Bitcoin product serving German-speaking customers. The DACH-specific naming layer is structurally undervalued compared to English-language equivalents.
.de is the largest country extension in Europe and the default trust signal for German customers. A German buyer landing on a .de assumes local jurisdiction, local support and local liability — assumptions a generic extension has to earn instead.
For a Bitcoin business that matters twice over: the product is unfamiliar to most of the market, and the extension removes one layer of unfamiliarity before the page has finished loading.
