Guaranteed Returns Scam: Any Promise of 20%+ Annualized Is a Scam

Someone tells you “invest XX project annualized 30% guaranteed returns”—if truly 30% annualized guaranteed returns existed, banks would’ve poured all money in. Any promise of 20%+ annualized guaranteed returns is a scam.

Why High Returns Can’t Guarantee Principal

• BTC annualized volatility approximately 70%—even the “safest” crypto can’t guarantee principal
• ETH staking annualized 4-5%—has slashing risk and price波动 risk
• DeFi lending annualized 3-10%—has contract risk and liquidity risk
• Annualized 20%+ guaranteed returns → violates fundamental financial law

Risk and return are positively correlated—high returns must accompany high risk. Guaranteed principal means zero risk, zero risk can’t have 20%+ returns.

5 Types of Guaranteed-Return Scams

1. Ponzi Scheme

Using new investor money to pay old investor returns. Looks “stable returns” actually paying前面 people with后面 people’s money. Collapses when new investors减少.

2. Fake DeFi Earn

Promises high-yield DeFi earn platform, actually no real lending business just Ponzi. Returns come from new user deposits not真实 lending spreads.

3. Fake Quantitative Trading

Claims using quantitative strategies稳定盈利 20%+, actually no trading strategy only using deposits to pay returns.

4. Fake Mining Rental

Claims renting miners获得 stable returns, actually no miners using rental fees to pay “mining returns.” New rentals减少后 collapses.

5. Fake Bank/Fund

Claims to be crypto bank or fund providing stable returns, actually scam.

Identification Methods

• Annualized >20% and guaranteed → 100% scam
• Doesn’t explain return source → extremely likely scam
• Returns come from “new user deposits” → Ponzi scam
• No independent audit → can’t verify真实性
• Withdrawal困难/requires lock-up → scam特征

Historical Guaranteed-Return Scams

• BitConnect: Daily returns 1% (365% annualized) → Ponzi → collapsed
• PlusToken: Monthly returns 10-30% → Ponzi →跑路
• C2C trading earn: Annualized 30% → Ponzi → collapsed

Why Guaranteed Returns Violate Financial Laws

Law 1: Risk-return positive correlation High returns must accompany high risk → guaranteed principal = zero risk → zero risk can’t have high returns → “guaranteed + high returns” = logical contradiction

Law 2: Risk-free rate benchmark Global safest investment (US Treasury) annualized approximately 4-5% → any returns exceeding risk-free rate accompany risk → annualized 20% means承担 risk far above Treasuries → can’t “guarantee principal”

Law 3: Market efficiency If truly 20% annualized guaranteed returns existed → global funds would涌入 → yields必然下降 → “20% guaranteed” can’t持续 exist

These three laws are economics’ fundamental truths → any investment promise violating these laws is a scam → no exceptions.

Reasonable Investment Alternatives

If you want relatively stable returns (not pursuing暴利 but不想亏太多):

1. ETH Staking: Annualized ~4-5%, has slashing and price risk, but真实 returns
2. DeFi Lending: Annualized ~3-10%, has contract risk, returns随 market波动
3. Stablecoin Earn: Annualized ~2-5%, has platform risk, yields较低 but相对稳定
4. BTC DCA: Long-term BTC holding, returns depend on BTC price, has historical growth trend

These alternatives yield much less than “promised 20% guaranteed” but risks真实可控—don’t guarantee principal because honestly面对 risk—this is真正的 investment.

Summary

Remember one iron rule: Any promise of 20%+ annualized guaranteed returns is a scam. No exceptions.
