Cryptocurrency books aimed at novice users or non-users tend to follow a very similar pattern. Almost all start with an obligatory “history of money” and explain why fiat is, let's say, "flawed," — to be polite. Then Bitcoin (BTC) in introduced, wielding a fistful of shiny new tech that can address some of these issues.
The books go into mining, wallets, exchanges, Ethereum and smart contracts, altcoins and decentralized finance — also known as DeFi. Once the authors are sure that the reader is sold on the idea of buying into crypto, they wrap it nicely up with a (foregone) conclusion and settle smugly back down.
