Turning a few thousand yuan of principal into a million-level sum in the crypto market? Many would say this is a fantasy, but the rolling position model does provide a chance for small funds to chase high returns—of course, the risks are equally off the charts.

Here's a case I saw: a trader started with $500 (about 3,500 RMB) and rolled it into over $100,000 in just two days. Sounds unbelievable, but breaking down his operations shows that this wave of profits was built on three key decisions.

**First trade:** Used 60% of his position to go 100x long on ETH, with a position value of about $30,000. The timing was spot-on—an American official suddenly announced that the probability of the SEC approving an Ethereum ETF jumped from previous expectations to 75%. This news instantly ignited the market, and ETH surged nearly 20% in a single day. He almost captured the entire rally, boosting his account from $500 to $6,000.

**Second trade:** Riding the momentum, he used 50% of his $6,000 to go long again (still 100x leverage), catching another 3% gain. At this point, his account balance reached $15,000.

**Third trade:** He switched strategies, targeting a small-cap coin in an uptrend channel. This time he lowered the leverage (20x), opened a position with $11,000, with a position value around $70,000. This trade yielded another $80,000 in profit.

After these three trades, $500 rolled up to over $100,000.

But to be honest, this kind of approach is more like "survivor's narrative"—you only see the successful cases, not the countless people who got liquidated. High leverage + heavy positions + chasing gains repeatedly, a mistake in any step could mean going straight to zero. The market won’t always move at your pace.
