Many people are curious about the same question: why can some traders consistently extract profits in both bull and bear markets? The answer often exceeds expectations—because they are not simply "speculating on coins," but rather doing business with probabilities.

**Treat the exchange like a casino, but be the house**

This idea is supported by mathematics. In the short term, fluctuations are driven by luck, but over longer timeframes, probabilities will dominate everything. The fundamental difference between gamblers and casino owners lies in mindset modeling—gamblers rely on luck for a single flip, while casino owners rely on the win rate structure of each bet to accumulate profits.

A classic comparison: ordinary traders chase highs and lows, barely achieving a 50% win rate with a 1:1 profit-to-loss ratio, which inevitably leads to long-term losses. But if a strategy has only a 35% win rate, yet sets a stop-loss at 1 dollar for every 5 dollars gained, the mathematical expectation instantly turns positive—35% × 5 - 65% × 1 = 1.75 - 0.65 = 1.1, creating a positive expected value.

**Core practical steps: three steps to build stable withdrawals**

The first step is crucial—before placing an order, ask yourself two questions. Can the stop-loss be set at 1.5% of the principal? Can the take-profit reach 5%? If neither condition can be met, just pass—this trade isn't worth doing. It’s like playing cards: if your hand isn’t good enough, don’t bet.

The second step is profit locking. When a single trade reaches 10% profit of the principal, immediately transfer half of the profit to a cold wallet. Why is this effective? Because it addresses two scenarios simultaneously—if the market continues to rise, the remaining half of the profit continues to compound; if the market suddenly pulls back, the profits already secured become permanent gains, preventing them from being swallowed back and eroding the principal.

This system has been tested since 2018, starting with 5000 USD, experiencing the era of contract liquidations, and observing the risks of information warfare. The final result is a stable annual account growth, unaffected by single shocks.

There are no secrets in trading, only discipline. Probabilities reward those who respect mathematics.
