# 9000U rolled to 140,000! The 4 core principles of the rolling position system in the cryptocurrency market, discipline is the key to profit
I suggested he change his strategy: never exceed 30% of a single position, decisively take profits at 10%-15%, and immediately stop loss if losses exceed 4%, firmly avoiding ambiguous trends.
At first, he found it hard to adapt, but he gritted his teeth and persisted in execution, reviewing daily, summarizing what went well and where mistakes occurred. Unexpectedly, after three months, his account balance grew from 9000U to nearly 140,000.
Later he told me: "It really isn't about luck, discipline saved me."
People often ask me, what is the most difficult thing in the cryptocurrency market? I always feel: it's not the technical analysis, not the insider information, and certainly not so-called 'talent', but whether one can stick to their own rhythm and not be swayed by market emotions.
This set of 'rolling position system' that I often share has had intuitive effects for many who have executed it, with 4 simple and practical core points:
## 1. Flexible position control, leave room for maneuver
Control the proportion of a single position to 20%-30%, even if one judgment is wrong, there is enough room for maneuver, so as not to lose everything, always leave yourself a chance to restart.
## 2. Take profits quickly, strictly control losses
Realize profits of 10%-15% in a timely manner, do not be greedy for the ultimate high point; if losses reach 3%-4%, stop loss must be immediate, preventing losses from expanding and guarding the capital baseline.
## 3. Follow the trend, refuse to predict
Firmly avoid bottom fishing and peak touching operations, wait for the market direction to become clear before entering. It may seem slow in rhythm, but in reality, the winning rate is more stable, avoiding being deceived by false signals.
## 4. Daily review, calibrate rhythm
Summarize daily trades, timely adjust position ratios and entry timing, form a positive cycle of profit through strict discipline, and the more you do, the smoother it becomes.
The market changes every day, but iron discipline will never go out of style. Many people cannot turn things around, not because they lack opportunities, but because their mindset and strategy remain stagnant. Stick to the rhythm, execute discipline, and profits will naturally come in slowly.
