In 2019 I published my first book: Crypto Nation Switzerland. I wrote the book in German for the Swiss market only (a bit of a mistake I must admit). Typically between 12,000 up to 15,000 books get published in Switzerland each year. Normally crime stories are among the bestsellers. Selling more than 5,000 copies in Switzerland is already outstanding. Therefore as a first-time author I am exceptionally proud to have sold so far almost 500 books. A big thank you to all my readers and my publisher Stämpfli Verlag in Bern.
