I still remember entering a position in Bitcoin for the first time in 2015 with 1000 yuan of living expenses. Back then, one was 3000 yuan, I bought 0.3, and for the next three days, my sleep was fragmented, averaging checking the price every hour.

In the span of ten years, I have witnessed too many roller coasters. From initially being a novice to my account reaching seven figures, what I am most proud of is not how much I earned, but that I have never been liquidated.

Many people say I am lucky or have a keen sense. In fact, it's not true. I have just slowly figured out a method of "discipline rolling". Today, I will share with you the three iron rules of this method, all of which were learned through real experience.

**Rule 1: Only eat meat, don't gnaw on bones - a one-sided trend is your ally**

The fundamental logic of rolling positions is to "leverage the market's momentum to amplify returns," rather than necessarily going against the trend. I have done statistics, and unilateral trends in the crypto market account for less than 30% of the time, yet during this 30% of the time, more than 70% of the returns are generated.

When should you take action? A clear entry signal occurs when there is a breakout from the main resistance or support level on the daily chart, with trading volume surging over 30%. But during sideways consolidation? That's the graveyard for rolling positions, and using high leverage at this time will only lead to repeated stop losses.

I suffered this loss back in 2018. During that time, I was stubborn and repeatedly opened positions while the market was sideways. After making 6 counter-trend trades, my 3000 yuan shrank to only 120 yuan, and I almost had to say goodbye to the crypto world. Since then, I set strict rules for myself: if the 4-hour K-line volatility is less than 5%, I wait in cash, and I firmly avoid trading unless I see 3 consecutive K-lines in the same direction. This discipline has saved me many times.
