Estimated Loss: ~$8 million
The Pitch: 50% returns in 45 days, allegedly from postal reply coupon arbitrage.

2. Sarah Howe – “Ladies’ Deposit” (1879)

Estimated Loss: ~$500,000

10 Red Flags of a Ponzi Scheme

Red Flag	What to Watch For
1. Unrealistically high returns	“Risk-free 50% monthly returns”? Nope.
2. Unrealistically steady profits	Markets fluctuate—it’s normal.
3. Lack of registration	Check SEC, FINRA, or CFTC databases.
4. Secretive or “proprietary” strategy	Legit funds show audits.
5. Poor auditor or no audit	If no independent audit, walk away.
6. Aggressive recruitment/new money needed	Pyramid-style referral pressure.
7. Withdrawal delays or restrictions	Difficult to cash out? Red alert.
8. Exclusivity-based persuasion	“Privileged access” culture = bad sign.
9. Promoters flaunting lavish wealth	Yachts and flash cars are funding early investors.
10. Missing or vague documentation	No records = no legitimacy.

(These warnings are echoed by regulators like the CFTC

How to Protect Yourself

• Verify registrations with FINRA, SEC, or CFTC.

• Insist on audited reports from reputable third parties.

• Demand transparent investment strategies you can verify.

• Be skeptical of promises of guaranteed returns.

• Test withdrawals before committing significant funds.

• Diversify into legitimate, regulated investments like stocks, bonds, and managed futures.

Final Takeaway

From Ponzi’s 1920 scam to Madoff’s staggering downfall, history is clear: If it sounds too good to be true, it probably is. The most effective defense is due diligence – know who you’re investing with, understand how they generate returns, and verify every claim.
