I have experienced too many incredible stories. An account starting with a few thousand yuan, growing to a million-level in just half a year, and the entire circle was talking about his legend. And then? A single unwillingness to take profits led to a wave of market movement wiping everything out.

This is the double-edged sword of position rolling.

**Why small funds can quickly amplify**

The magic of position rolling lies in the compound interest effect. When you judge the right direction, instead of taking floating profits, you continue to add positions. Profits grow like a rolling snowball. In a favorable market trend, this strategy can rapidly grow the account to an astonishing scale.

But this is also the most dangerous part—people often overestimate their ability to grasp the trend.

Once the market reverses, the same leverage can destroy the account at ten times the speed. This is not alarmist; it’s the reality played out every day in the market.

**The core logic of position rolling is actually simple**

Use existing profits to bet on larger trend movements.

When the trend is in your favor, adding to floating profits is reasonable. You are using the market’s own money, not your principal. The problem is that most people cannot distinguish when to add and when to run.

When making money, a hallucination occurs—they think they truly understand the market and that this wave of trend can continue infinitely. They ignore all risk signals until they are forced to sell and wake up.

When losing money, it’s a different story. They refuse to admit mistakes, fantasizing about holding on until they break even. In reality, every hesitation and lucky guess accumulates risk. Eventually, a sudden shock will wipe out all chips.

**Those who survive follow these three bottom lines**

First, only participate in clear trend markets. No participation during sideways movement—that’s crucial. Many accounts are wiped out not by big market moves, but by repeated wear and tear in choppy markets. When the trend is uncertain, the smartest move is to hold cash.

Second, take profits in stages. This may sound boring, but it’s very effective. Every time you earn 30% profit, take half out first, transferring it to a spot account or stablecoin account. The remaining part should have a trailing stop-loss set, allowing floating profits to continue running but preventing a direct fall from heaven to hell.

Third, leave room for positions. The initial position should never exceed 10% of the account. Even with subsequent additions, control within 20% of total funds. Never go all-in. This approach may seem slow, but it allows you to survive longer. In this market, those who survive longer tend to earn the most.

**The real enemy is yourself**

Skills can be learned, market intuition can be cultivated, but human nature is hard to change.

Greed will make you continue fighting when you should take profits, turning floating gains into floating losses. Fear will make you hesitate at the point of stop-loss, dragging it out repeatedly. Overconfidence will cause you to repeatedly operate in choppy markets without a trend, getting slapped back and forth.

The most common way to die in the market is not being swept out by a big trend, but dying in countless small wear and tear.

**Final words**

Opportunities in the crypto market are always there, but fewer and fewer people survive to see them. Position rolling is not about who earns faster, but about who can survive longer. As long as you are still at the table, the next wave of trend will always belong to you.
