Honestly, digital asset contracts are not as simple as they seem — they can be lightning-fast to make money, and just as quick to lose it all.

I once led a few partners to turn over a principal of just over 1000U into 100,000U, relying not on luck but on five strict rules learned through blood and tears.

My approach back then was indeed very aggressive: dividing 1500U into three parts, each with 500U, using 100x leverage. Just one point move could double the position, and if wrong, that 500U was just tuition. Surviving such high-risk operations was purely due to discipline.

**Rule 1: Stop-loss must be ruthless, never soft.**

In my early days, I twice blew up positions waiting for rebounds. After that, I set an ironclad rule — once the stop-loss is hit, exit immediately. Accepting a loss is always better than holding on and being swept away in one wave.

**Rule 2: Stop after five consecutive losses.**

When the market is chaotic, stubbornly fighting is suicidal trading. I set a "circuit breaker": after five wrong trades, shut down the program, leave the screen, and cool off for a night. You’ll be surprised to find that the next day, the market’s trend often becomes clear.

**Rule 3: Take profits immediately, don’t let account numbers blind you.**

Unrealized gains are illusions. My rule is to take half of the profit once it reaches 6000U; only when the funds are transferred to the wallet does it count. This way, your mindset won’t be affected by fluctuating numbers.

**Rule 4: Only trade in one-way trends, never engage in sideways markets.**

In a trending market, 100x leverage is an accelerator; in sideways markets, it becomes a meat grinder. When the direction is uncertain, staying in cash and waiting is always better than guessing blindly.

**Rule 5: Control your position size, never go all-in.**

Only trade 500U per position, and never risk more than 10% of your principal overall. Light positions keep your mind clear, and even if you lose, you won’t be hurt badly.

Contract trading is never a quick path to overnight riches; it’s fundamentally a endurance race. Opportunities in the crypto world are plentiful, but traps are even more numerous. Only by engraving these five rules in your heart can you reach the end and leave with a smile.
