[The Disruptive Truth of Trading]
Leverage is a blunt knife; position is the sharp spike that kills.
Using 1% position under 100x leverage, the risk is even lower than a full position in spot trading—just like trying to chop a tree with a fruit knife, no matter how sharp the knife is, the force behind the swing determines the damage. My students who used 20x leverage on ETH, each time only risking 2% of their principal, have not seen a liquidation screen in three years, while their accounts have snowballed from 20,000 to 680,000.

Stop loss is not cutting losses; it’s buying insurance for the account.
During the 312 crash in 2024, 78% of those who got liquidated were holding on stubbornly—they didn’t know that a single loss exceeding 5% is like driving without a seatbelt. The iron rule for professional traders is: each trade can lose a maximum of 2% of the principal, which is like installing a fuse for the account; burning it once only injures the surface and will never cause a total blackout.

Rolling positions is not all in; it’s using profits to build a ladder.
How to play with 50,000 principal? The first position is 10% for trial and error (5,000 yuan). For every 10% profit, use 10% of the profit to increase the position. When BTC rises from 75,000 to 82,500, this method only expands the total position by 10%, but increases the safety margin by 30%—just like climbing stairs, stepping steadily on one step at a time is actually faster than jumping to the top.

Dynamic Position Calculator (Even elementary school students can calculate)
Total Position ≤ (Principal × 2%) ÷ (Stop Loss Margin × Leverage Ratio)
▷ Example: 50,000 principal, set 2% stop loss, use 10x leverage
▷ Formula: 50000 × 0.02 ÷ (0.02 × 10) = 5000 yuan
▷ Remember: The calculated number is the ceiling; betting even one more yuan is gambling with your life.

Three-step Take Profit Method (Put money in your pocket in three times)
① Sell 1/3 when earning 20% → Secure starting capital.
② Sell another 1/3 when earning 50% → Preserve the safety net of most profits.
③ The remaining 1/3 follows the 5-day moving average → Let the profits ride the wind.
▷ In the halving market of 2024, this method turned 50,000 into 1,000,000, equivalent to earning 19 times with 10% of the principal.

Hedging Insurance (Spend a small amount to protect a large amount)
Use 1% of the principal to buy Put options, which can hedge against 80% of black swan events—during the flash crash in April 2024, while others' accounts were halved, I preserved 23% of my principal with options. It's like spending a few hundred yuan to buy full insurance while driving; it can save your life in case of an accident.


[Deadly Traps Exposed by Data]
- Holding positions for more than 4 hours? 92% of people will be liquidated—equivalent to sleeping in a minefield.
- High-frequency trading 500 times a month? 24% of the principal will be eaten by transaction fees—it's even harsher than a casino's cut.
- Made money without taking profit? 83% of people will give it all back—like holding sand in your hand, the tighter you grip, the more it leaks.


[The Mathematical Code of Trading Essence]
Profit Formula: Expected Value = Win Rate × Profit Margin - Loss Rate × Loss Margin
When you set a 2% stop loss and a 20% take profit, you can make money with just a 34% win rate—meaning winning 3 out of 10 trades is enough to break even. Professional traders compress the stop loss to 1.5% and raise the take profit to 15%, achieving an annualized return of over 400% with this formula, just like using a better tool in a casino.

[The Four Strategies of a Seven-Year Trader]
1. Single Loss ≤ 2% → Never lose more than a meal's worth, never injure your core.
2. Only 20 trades per year → Wait like a cheetah; when you act, it’s a killing move.
3. Win-Loss Ratio ≥ 3:1 → Earning 3 times is enough to cover 1 loss, making it easier as you play.
4. 70% of the time in cash → 90% of market fluctuations are noise; don’t waste bullets.

[The Last Bowl of Poisonous Chicken Soup]
The market is not an ATM; it’s a probabilistic casino. I’ve seen too many people make 10 times with 10% of their position, only to lose everything in a single 20% position operation—remember: controlling losses is not cowardice; it’s to survive to see tomorrow's sun. When you can calculate the stop loss before every order, congratulations, you have already beaten 80% of traders.
