Contract trading is arguably the most brutal game in the crypto world—miracles of doubling in three days and tragedies of going to zero overnight have all played out in reality. I started with 1,000 yuan and turned it into 100,000 in three months, but more importantly, I discovered that surviving isn’t about luck, but about a few core bottom-line rules that must be etched into your mind.

**The essence of position rolling: using rules to suppress human greed**

In the early stages of testing the waters, I started with $300, opening only 10-dollar contracts with 100x leverage each time. The allure of leverage is that a 1% move in the right direction can double your principal, but in reality, 90% of traders get caught in three traps—being reluctant to close profits and wanting to keep earning, adding aggressively after losses to recover quickly, and frequently switching between long and short positions, only to be slapped in the face by the market.

My approach is straightforward: take 50% of profits each time and withdraw it, rolling over the remaining profits. In theory, winning 11 times in a row could turn $10 into $10,000, but only those who turn their stop-loss and take-profit into conditioned reflexes can truly execute this.

**Five ironclad rules engraved in the mind**

**Rule 1: Stop-loss equals survival.** Many early blow-ups came from the self-deceiving phrase—"It will rebound." Later, I changed the rule: stop-loss is triggered immediately, no matter how unwilling I am. Compared to proving my judgment correct, surviving is a hundred times more important.

**Rule 2: Warning line for consecutive losses.** After 20 consecutive wrong trades (even losing only $10 each), I stop trading for the day. When the market is out of control, watching calmly is more life-saving than reckless trading.

**Rule 3: Mandatory profit withdrawal.** When the account reaches $5,000, I must withdraw at least half of the profits. During last year's Ethereum one-way rally, I rolled from $500 to $500,000, and deliberately withdrew $200,000 midway—this decision helped me preserve most of the gains during subsequent pullbacks, avoiding the rollercoaster wipeout others experienced.

**Rule 4: Only target one-sided trends.** In choppy markets, 100x leverage is a death sentence. I once waited four months without opening a single trade, just to wait for a clear trend opportunity. When I saw it, I executed precisely. Usually, pretending to be dead is the safest strategy.

**Rule 5: Position limit of 10%.** With a $1,000 capital, I never open more than $100 per trade. Light positions mean that even big fluctuations won’t crush my mindset; full positions, however, mean that even 9 correct trades can be wiped out by 1 mistake.

**From data to practical combat**

All these rules come from real lessons learned with real money. Turning $300 into $10,000, or $500 into $500,000 sounds glamorous, but behind it are countless near-collapse moments forced into stop-loss. Contracts are like a mirror—what they amplify isn’t your intelligence, but your greed and fear.

Many ask me why I don’t go all-in, add to positions, or hold on stubbornly. The answer is simple—full positions give only temporary pleasure, but the pain of zeroing out lasts a lifetime. In this market, just surviving is already winning more than half the battle.
