#美国核心物价涨幅不及市场预估 The Hidden Risks Ignored in Contract Trading—The Harvesting Tricks of Funding Rates

I've seen many traders fall into the same trap. A friend started with $12,000 USD last year and, during the altcoin craze, traded his way up to $35,000 USD, proudly claiming his trading talent. But it didn't take long before he was left with only $2,300 USD, looking confused and asking, "Why did my money just disappear?"

Where was the problem? Funding rates.

He was heavily invested in a few small-cap coins with high control, where the rate was as high as 1.8% per hour. That translates to nearly 20% of margin being deducted daily. The most ironic part is, the coin prices didn't move at all, but his account was drained dry. In the end, the market makers dumped the price, and his account was wiped out.

This is the full picture of the scam in the altcoin market: small-cap coins with highly concentrated holdings and low liquidity, initially attracting retail traders with low fees, then market makers violently pushing the price up. Once the contract price far exceeds the spot price, they push the funding rate to absurd levels. In this "vampiric" state, even if the trader's direction is correct, they can be dragged down by the funding rate.

The key issue is that retail traders often see high funding rates as a sign of a strong upward trend, and stubbornly hold on, increasing their losses.

What was the turning point? Giving up on altcoins and switching to mainstream coins like $BTC and $ETH. He followed three basic principles:

First, avoid any coin with a funding rate exceeding 0.5%. Mainstream coins have relatively stable and reasonable rates, leaving no room for malicious market maker manipulation.

Second, always include the funding cost in each trade. Use this to determine reasonable stop-loss points, strictly controlling single-trade losses to no more than 1% of the principal.

Third, only trade on daily trend charts. Short-term chasing can trap you in many false signals; extending the time frame helps effectively avoid this.

How effective was it? During the first half of the year, when $ETH rose from 2600 to 3500, he participated with a small position, and the impact of funding rates was minimal. He made $5,800 USD profit on a single trade. Over the next two months, his remaining $2,300 USD gradually grew to $21,000 USD.

Later, he removed the labels of "genius trader" from his social media circles, and gained a deep insight: "The invisible funding rate trap is more terrifying than any crash."

Most retail traders mistake luck for skill in trading but overlook the deadly hidden costs in the structure. The scythe of high-control small-cap coins is hidden in seemingly tiny details—each hourly deduction, each hidden cost.

Want to survive longer in the crypto world? Stay away from small coins with excessively high fees, focus on trend trading of mainstream coins, calculate every cost clearly, and give up the short-term quick money dream. This is the stable trading logic.
