A group of investors, referred to as 'cryptobros', spent €2.6 million on a book at an auction, believing they would own the copyright. However, they only acquired the physical book, not the intellectual property rights. The book is a storyboard for the film 'Dune' and was sold at a significantly higher price than its estimated value. The buyers intended to turn the book into NFTs and potentially sell the rights to a streaming service.
