The four-part online seminar is very well organized, structured, and documented. It gives you a good impression of how Bitcoin works and what the opportunities and risks are. Thank you very much, Jürg.

BS fully met my expectations: - highly competent staff - proper explanation and guidance through the process (e.g. BTC wallet) - full transparency regarding opportunities and challenges - business model in line with regulatory Switzerland-specific requirements - willingness of the Management to understand the client's needs I am looking forward doing more business with BS.

I can absolutely recommend Jürg's seminars. He doesn't present Bitcoin as a trading topic, but rather as a solid foundation of knowledge – exactly what I think most people lack. I especially appreciated that he deliberately structures the course at a comfortable pace and strongly addresses the needs of beginners. This is extremely helpful, particularly for people over 50, because nothing is rushed and you truly understand how Bitcoin works, instead of just hearing buzzwords. I learned a great deal in a short time – especially with practical and easy-to-understand explanations. Anyone who wants to understand Bitcoin seriously and isn't looking for quick profits will find this seminar invaluable. Highly recommended.

I wholeheartedly recommend Jürg Kradolfer's Bitcoin course! Are you looking for in-depth knowledge and practical insights into the world of Bitcoin? Then you've come to the right place. Jürg Kradolfer is not only incredibly competent, but he also explains complex topics in such a clear and inspiring way that you immediately feel engaged. The course content was exceptionally well-structured and covered all the important aspects. I can recommend this course to anyone who wants to gain a solid understanding of Bitcoin. A worthwhile investment!

Review of the current (Fall 2025) online seminar "Understanding and Applying Bitcoin and Blockchain": The seminar is clearly structured, offers broad information on Bitcoin and blockchain, generally doesn't go into extreme technical detail (which certainly makes it more enjoyable for some seminar participants), and allows enough time to answer questions before, during, and after the meeting. This is especially important here, as the seminar participants (in my case) are thoughtful, which is why they also ask interesting questions – questions that I often wouldn't have immediately thought of myself. Jürg Kradolfer manages to answer the questions simply and clearly. I recommend that future seminar participants take plenty of notes during the four 2-hour meetings. Even though there is a brief review of the previous week, some interesting information is still gathered.

The online seminar by Bitcoin Switzerland's Jürg Kradolfer was extremely beneficial in several respects. Even we, as "older retirees," were able to follow the course perfectly. The seminar isn't just for young people; we older people benefited from it as well. Nothing is sold to you, nothing is sugarcoated; it's completely honest, which is something you don't always find these days. The Wil Adult Education Center offers this seminar. We highly recommend it.
