"Isn't investing just gambling?" — This one book will put that fear to rest

"Savings alone won't secure my future, but investing sounds terrifying." "There's too much noise on YouTube and social media — who do I trust?" Sound familiar?

Here's the thing: that very anxiety is the #1 reason people fall for investment scams. Without the right knowledge, panic leads to bad decisions. But flip the script — once you have a clear framework for spotting fraud, investing becomes one of the safest ways to grow wealth.

"Manga de Wakaru — Damasarenai Okane no Fuyashikata" (by Sho Toriumi) — roughly translated as "The Manga Guide to Scam‑Proof Wealth Building" — hands you that framework in the easiest format possible.

Three reasons you should read this book

Reason 1: It's manga — you will actually finish it

The biggest failure mode with investment books? Buying one and quitting halfway. Dense text plus formulas equals instant boredom.

This book is 100% manga. A beginner protagonist learns from a mentor character, story‑arc style, so it reads like a drama — not a textbook.

• ✅ Easy to follow even if you hate reading
• ✅ Jargon is explained in‑context — no glossary needed
• ✅ One chapter per commute or bedtime session

If you've never finished an investment book, this is the one to start with.

Reason 2: You gain a "scam‑proof" thinking framework

The book's biggest value isn't telling you what to invest in — it teaches you what NOT to invest in.

Author Sho Toriumi systematically breaks down how to spot fraud and overpriced financial products:

• 🚫 "Guaranteed returns of 20% p.a." = always a scam
• 🚫 How Ponzi schemes disguise dividend payouts
• 🚫 Why "easy money" pitches on social media are red flags
• ✅ Three conditions every trustworthy investment must meet

Even if you actively trade FX or crypto, the "portfolio foundation" mindset for stable assets is incredibly valuable.

Reason 3: The "auto‑pilot ¥100K/month" system is concrete and actionable

"Auto‑pilot" isn't a lazy shortcut — it means building a system that runs itself once set up.

The book outlines:

1. Index fund DCA (dollar‑cost averaging) — diversify across the market and let time compound
2. Dividend strategy — use high‑yield ETFs to create recurring cash flow
3. Rule‑based rebalancing — remove emotion from buy/sell decisions

Combined, these give busy professionals and side‑hustle traders a clear roadmap to ¥100K/month in passive income.

Why FX and crypto traders need this book too

"I actively trade FX and crypto — I don't need a beginner book." If that's what you're thinking, hear me out.

Active trading and long‑term stable investing are offense and defense. When your trades are profitable, where you park those profits determines your net worth in 5–10 years.

Learning the "defensive investing" in this book lets you:

• 🔄 Set rules for reinvesting trading profits safely
• 📉 Maintain psychological stability during volatile markets
• 💰 Keep your wealth intact even if you stop trading

The bottom line: knowledge is your first (and cheapest) investment

The most dangerous thing in investing is starting without knowledge. The simplest defense? Read one book.

"Manga Guide to Scam‑Proof Wealth Building" gives you:

• ✅ A manga format you will actually finish
• ✅ A framework to spot fraud and overpriced products
• ✅ A concrete roadmap toward ¥100K/month passive income

For roughly ¥1,500, you can acquire a lifelong "scam‑proof" mindset. Isn't that worth it?
