According to CoinMeta, as reported by CryptoNews, more and more readers are beginning to pay attention to educational cryptocurrency books that explain the basic principles of Bitcoin, going beyond price charts and market speculation. After reaching a historical high of nearly $69,000 in November 2021, Bitcoin fell to $16,000 by November 2022. A decline of about 77% left many still unable to understand why the supply is limited to 21 million coins. Understanding scarcity, consensus, and self-custody is key to comprehending Bitcoin, rather than just focusing on price targets or trading settings. The book "Why Choose Crypto?" written by Heidi Chacos aims to help readers understand how Bitcoin works, beyond just price fluctuations.
