"So what's actually special about Bitcoin?" — The book that answers what everyone's too embarrassed to ask
"Bitcoin is apparently going up, but I don't really understand how it works."
"I've heard the word 'blockchain' but couldn't explain it if I tried."
"NFTs, DeFi — are they irrelevant now, or just getting started?"
Sound familiar?
You're curious about crypto, but asking basic questions feels embarrassing at this point. That's completely understandable — and also a huge missed opportunity. Because in 2026, with Bitcoin ETFs approved globally, CBDCs going live in multiple countries, and stablecoin regulations taking shape, cryptocurrency has evolved from speculation to infrastructure.
Now is exactly when you need to read "Imasara Kikenai Bitcoin to Blockchain — Latest Revised Edition" by Yusuke Otsuka.
Reason 1: The author is Coincheck's former COO — insider knowledge you can't get anywhere else
Investment books are published by the dozens every month, but books written by crypto exchange executives themselves are extremely rare.
Author Yusuke Otsuka co-founded Coincheck, one of Japan's largest cryptocurrency exchanges, and served as COO. He's someone who has seen crypto from the operator's side of the counter.
✅ He knows what happens behind the scenes at an exchange
✅ He lived through the 2018 NEM hack as a company executive
✅ He worked directly with Japan's Financial Services Agency on regulation
This means the explanations go far beyond textbook definitions — you get real, battle-tested insights from someone who built the industry.
Reason 2: A systematic understanding of the future of finance — the world beyond Bitcoin
Most crypto beginner books stop at "how to buy Bitcoin." This one doesn't.
Otsuka paints a picture of the future of money itself — and that scope is what separates this book from every other introduction:
🔗 The essence of blockchain — Why "decentralized" could actually replace banks
🌐 DeFi (Decentralized Finance) — Financial services without a bank account
📦 NFTs and token economics — How digital ownership reshapes the economy
🏛️ CBDCs (Central Bank Digital Currencies) — When and how the digital yen becomes reality
⚖️ Web3 and the regulatory frontier — Latest topics added in the 2025 revision
For FX and stock investors, this is crucial context: understanding how finance will change over the next decade directly impacts your investment strategy. The transformation is happening now.
Reason 3: 336 pages at this price — the value proposition is unbeatable
Let's be honest: this book costs around ¥1,000 (under $10).
A comprehensive 336-page guide by a crypto industry pioneer, for the price of lunch. That's exceptional value.
Crypto seminars cost tens of thousands of yen. YouTube information is fragmented and impossible to learn systematically from. This book gives you:
📚 Complete, structured knowledge in a single volume
🔄 A reference you can revisit anytime (also available as an e-book)
🛡️ A solid foundation that protects you from misinformation
As an investment in knowledge, you won't find better ROI.
Recommended for crypto traders AND FX/stock investors
"I already own Bitcoin — I don't need this." If that's what you're thinking, consider this:
Owning and understanding are two very different things.
Can you logically explain why Bitcoin's halving cycle affects its price?
Do you understand what Ethereum's Proof-of-Stake transition actually changed?
Can you articulate the risk-reward structure of DeFi lending?
Understanding these systematically changes how you position, sharpens your stop-loss decisions, and deepens your conviction for long-term holds.
For FX and stock investors, crypto market movements are an increasingly important factor affecting forex and equity prices. Eliminating "unknown asset classes" from your blind spots is key to improving overall investment performance.
The bottom line: "too late" is actually the perfect timing
Bitcoin ETFs approved worldwide. Nations rolling out digital currencies. 2026 is the year.
There's no such thing as "too late." Right now is the best time to learn.
"What's so special about Bitcoin?" — The answer is right here. Check it out now.
