"Bitcoin, what on earth is it that has the world paying attention?"

Let's take a look at what's happening in the United States, the world's most powerful country.
In 2024, the Bitcoin ETF launched and achieved unprecedented success in ETF history, and in 2025, President Trump officially designated Bitcoin as a strategic asset in the United States by executive order.
Since then, it has been adopted or is under consideration as a strategic asset in several states.

And numerous global companies around the world, including Strategy, a U.S.-listed company, and Metaplanet, a Japanese-listed company, are purchasing Bitcoin in droves.
So, what is it about Bitcoin that has been accepted by countries around the world?

But in our country, it is still considered only a means of speculation.
Many people, unaware of the true nature of Bitcoin, simply buy and sell, obsessing over price rather than value, losing sleep over the fluctuating numbers and increasing their losses.
Now we need to understand the essence of Bitcoin and approach it accordingly.

The answer is right here in this book.
Bitcoin is not just a digital asset.
Money that guarantees freedom and self-determination, decentralized, censorship-proof, scarce, and, above all, fully owned by individuals, is the first true money in the world.
The moment you understand its value, Bitcoin will become more than just an investment; it will become essential money for a free life.

Now, let's open this book.
The essence of Bitcoin, the money you need to know first, is contained here.
