"I started NISA, but is it really enough for my future?"
Japan's new NISA program has motivated many people to start investing. But a nagging doubt lingers:
"Will index fund contributions through NISA really cover my retirement?"
"Wealthy people must be doing something beyond NISA, right?"
"Bitcoin keeps coming up, but I always assumed it wasn't for me."
Here's a fact that might surprise you: 1 in 3 wealthy individuals have already begun investing in Bitcoin. In the US, 14% of the population holds crypto assets. Bitcoin is no longer a gamble — it's becoming the new common sense of asset building.
But "where do I even start?" — if that's your question, this book is your answer.
Reason 1: The author learned from catastrophic failure — zero ivory tower theory
What makes author "Rikuhiro" instantly relatable is his story.
He poured his entire savings from part-time college jobs into investments — only to lose everything when the 2008 financial crisis hit the following year.
From that devastating starting point, he spent 14 years studying finance and investing, ultimately reaching 50 million yen by age 30 and surpassing 100 million yen (approximately $700K+) in his 30s. Today he's a popular investor with 40,000 followers on X (Twitter).
💥 Experienced the worst-case scenario: losing everything in 2008
📚 Self-taught over 14 years of dedicated financial study
🏆 Built $1M+ in assets by his 30s, relocated to enjoy financial freedom
👥 40K X followers prove his ability to explain complex topics simply
This is why the book is filled with grounded, battle-tested advice that only someone who has failed catastrophically can write. The "grow your wealth while minimizing risk" philosophy comes from real, painful experience.
The crypto world moves fast, and outdated books contain outdated — sometimes dangerous — information.
This book was published in March 2024, meaning it covers:
🏛️ The historic approval of spot Bitcoin ETFs and what it means
📊 Why institutional investors are now paying attention to Bitcoin
💰 Asset-building strategies combining NISA and Bitcoin
🌍 Post-Trump inauguration crypto policy shifts
📈 How to generate passive income with Bitcoin — a method 90% of people don't know
2024 was arguably Bitcoin's biggest inflection point in history. ETF approval, the halving, political tailwinds — this book covers all of it with the latest information.
Reason 3: Absolutely zero jargon — readable even if you know nothing about investing
Have you ever tried reading a crypto book, only to hit a wall of jargon and give up?
"Hash rate," "proof of work," "private key" — a barrage of incomprehensible terms that makes you close the book after 3 pages. You're not alone.
This book commits fully to zero jargon:
🔤 Every technical concept translated into everyday language
📖 "So THAT'S what it means!" moments on every page
🎯 Basics to practice, complete in just one book
📱 Step-by-step guidance from opening an account to making your first purchase
At a comfortable 239 pages, it answers every single "where do I start?" question you have.
Why NISA users in particular should read this
"I'm already doing NISA — this doesn't apply to me." Hold that thought.
NISA is a wonderful program, but it limits your investments to stocks and mutual funds. This means your portfolio diversification might be insufficient.
📉 When the stock market crashes, your NISA assets go down with it
🌐 Bitcoin often moves independently of stocks — a genuine diversification option
💎 As "digital gold," Bitcoin serves as an effective inflation hedge
Learning the basics of Bitcoin as your "next move" beyond NISA is highly rational from an asset protection standpoint.
The bottom line: "I didn't know" won't cut it anymore
Bitcoin ETFs approved worldwide. Wealthy individuals and institutional investors adding it to portfolios. This is 2026.
The people who thought "this isn't for me" will be the same people saying "I wish I'd started sooner" in five years — a pattern that has repeated with stocks, with NISA, with every major investment opportunity.
"The Easiest Bitcoin Textbook in the World" delivers:
✅ Real-world wisdom from an author who rebuilt from financial ruin to $1M+
Whether you know about Bitcoin or not will determine the difference in your portfolio five years from now. Check it out today.
