Blocktrainer

Blocktrainer is a German-language Bitcoin education and news platform operated by Blocktrainer GmbH, based in Coesfeld, Germany. The brand was founded by Roman Reher, who built the original YouTube channel into one of the most followed Bitcoin-focused outlets in the DACH region. The platform sits firmly in the Bitcoin-only camp rather than covering the broader cryptocurrency market, and the team frames its work as journalistic and educational rather than as investment guidance.

The website hosts a wide range of reference content for German-speaking Bitcoin users. Beginners can work through structured tutorials on buying, custody, and tax topics, while more experienced users have access to comparisons of Bitcoin brokers, exchanges, hardware wallets, and steel-backup products. Blocktrainer also maintains a glossary, a research library covering monetary history and economics, and a German edition of widely cited resources such as the WTF Happened in 1971 reference. A daily news feed and a podcast round out the editorial side, and a community forum gives readers a place to discuss articles and ask questions.

Beyond articles and reviews, Blocktrainer publishes a set of calculators and tools tailored to Bitcoin users, including DCA savings-plan calculators, solo-mining estimators, UTXO dust analysers, transaction-fee calculators, and a halving countdown. The site also distributes original merchandise and curated Bitcoin books through its own shop. Roman Reher remains the public face of the brand, regularly commenting on German and EU policy developments affecting Bitcoin and self-custody, and Blocktrainer is widely regarded as one of the most influential independent Bitcoin voices in German-speaking countries.
