Recently, I received quite a few feedbacks from investors, which made me both want to laugh and get angry. Some people are attracted by platforms promising 40% annual high yields, transferring a BTC to earn interest, only to almost not recognize the amount when it arrives—0.00001088 BTC transferred, and only 0.0000588 BTC received. This isn't earning interest; it's clearly paying "referral fees" to scammers.

I myself fell into this trap early on in my crypto journey. Today, I will break down the tricks behind these high-yield scams so everyone can see clearly and avoid falling for them again.

**The First Layer of the High-Yield Promise Scam**

A 40% annual return sounds very tempting? But just think about how absurd that is. In legitimate crypto markets, reliable staking yields are usually within 10% annually, and products offering over 20% should raise suspicion. An exaggerated figure like 40%—frankly—is blatantly violating financial common sense.

No market can generate such high returns out of thin air. High yields inevitably hide high risks—either the platform itself is gambling or setting a trap to harvest investors' funds.

**Various Hidden Harvesting Tricks**

What's even more insidious is that platforms use various excuses to secretly deduct your earnings. Some freeze large "fees" or "channel charges" upon arrival; others simply set most of the 40% profit as "mandatory reinvestment," meaning you can't withdraw more than half of the earnings, and must keep locking it in the platform.

When you actually want to redeem or withdraw, a clause about "early redemption penalty" will pop up, and in the end, you might get less than your principal. That's why the BTC of that fan shrank—the seemingly reasonable "management fee" and "channel fee" are actually embedded in the platform's rules from the start.

**Misconceptions About Gas Fees**

Another point many beginners don't understand is that on-chain transaction Gas fees are based on computational load, not the transfer amount. Transferring 0.00001 BTC and 10 BTC incurs roughly the same basic fee; sometimes even identical. Some unscrupulous platforms exploit this by charging outrageous "service fees" for small transfers, claiming they are Gas fees, but in reality, they are inflated charges set by the platform itself.

**How to Make Safe Choices**

Want to participate in crypto yield projects? Remember: be cautious of products promising over 15% annual yields, and avoid those exceeding 25%. Choosing well-known, compliant, and regulated large trading platforms is more secure. Compared to small platforms promising astronomical returns, it's better to earn less but protect your principal.

Greed is the biggest killer in this market. Don't let a fleeting dream of huge profits ruin your entire investment plan.
