Cryptocurrency profits come quickly, but losses come even faster. I have proven one thing through my actual experience: in contract trading, luck is never the key; strict discipline execution is.

My trading style is indeed aggressive. I split 300U into 10 parts, using only 30U each time to open 100x leverage. When the market moves in your favor, a single point can double your money; when it goes against you, that amount is wiped out instantly. This approach may look like dancing on the edge of a knife, but the real secret to survival is actually those five bottom-line rules that you must never break.

**Bottom Line 1: Cut losses quickly, don’t hope for a rebound.** In the first two years of entering the market, I blew two positions because I kept thinking "wait a little longer, it will rebound." The market won't change direction just because of your expectations. When you hit the stop-loss level, it’s time to exit. Accepting a loss is always wiser than holding on and risking bigger damage.

**Bottom Line 2: After 5 consecutive losses, shut down and take a break.** When the market is unclear, continuous trading is like giving away money. I set a strict circuit breaker for myself: after 5 consecutive losses, I stop trading, turn off the screen, and rest for a day. Usually, the next day, the market clears up and the mind is refreshed.

**Bottom Line 3: Withdraw once you make 3000U.** The numbers in your account are floating and can evaporate at any moment. My rule is very strict: once I earn 3000U, I withdraw at least half. The money in hand is the real profit; paper gains are just illusions.

**Bottom Line 4: Only trade in one-sided trends, stay away from choppy markets.** In clear upward or downward trends, 100x leverage is an accelerator; but in sideways ranges, it becomes a harvesting tool. When there’s no clear direction, staying in cash and waiting is always the best choice.

**Bottom Line 5: Keep each position within 10% of the principal.** Going all-in with a full position can be deadly. I only use 30U each time, which I can afford to lose and also win steadily. Light positions help keep a calm mindset, preventing reckless operations.

These five rules are the reason I am still here today. Surviving in the contract market is even harder than making money. Embed these disciplines into your bones, and the rest is up to time.
