I feel like I'm in another world

I wonder if there is a "Blockchain, Bitcoin and Cryptocurrency" for Dummies book. I don't think I would get very far taking courses for this certificate "The Mastering Blockchain, Bitcoin and Cryptocurrency Certificate Accelerated Program provides learners with the knowledge, strategies, tools and skills needed for using blockchain, Bitcoin and cryptocurrency in the workplace. Blockchain and cryptocurrency skills are required in various fields, including government, health care, education, financial services, logistics, real estate, startups, oil and gas, the non-profit sector and business. Using a digital pedagogical approach that integrates theory and practical application, learners use blockchain tools, techniques and platforms to gain an understanding of this technology. Learners are provided with the essentials of blockchain technology, Bitcoin and cryptocurrency, including its origin, what it is, how it is being used, how to use it and how it can be used to add value to businesses and society. Also covered are important advanced topics, such as smart contracts, Non-Fungible Tokens (NFTs) and how they transform entire industries. This program includes three modules for a total of 108 hours. Graduates of the Mastering Blockchain, Bitcoin and Cryptocurrency Certificate Accelerated Program are qualified to write the Global Blockchain Professional (GBP™) exam from the Foundational Technologies Institute." And of course there is a Dummies book. I've put a hold on it from the library.
