When Bitcoin, a blockchain-based payment system, is mentioned, many think of how many poor, middle-class, and youth have become millionaires and even multimillionaires by investing in it. Blockchain has many potentials, described in this book, but one of its products is cryptocurrency, a decentralized online payment system.

The most popular cryptocurrency is Bitcoin, which the inventor of blockchain initially introduced. An individual who invested almost $1350 in 100 bitcoins in 2013, when the price of bitcoin was $13.5, owned nearly $6.5 million in 2021 and even more in 2024 due to the rise in bitcoin to $64 thousand over the eight years. That may be the beginning because fiat currencies have proven to perform poorly for long-term savings and investment.

However, this book's message is far beyond personal gain, and its worth extends beyond financial measurement. Many scratched the surface but never dug deeper to understand that blockchain is not a one-time personal financial gain but a lifetime of education and freedom.
