In 2021, a fan I brought along named 'A Shu' had just entered the crypto world for a year. He turned 10,000 capital into 200,000 without working, sending me travel locations every day.

Reviewing his strategy, it can be summed up in one sentence: treat leverage as a tool, not a gambling device.

Before entering the market, he converted 10,000 CNY to 1,375 U and only used 3x leverage.

Many people shake their heads when they hear 3x, thinking it's too slow;

A Shu calculated: the liquidation line for 3x is approximately a reverse fluctuation of 30%, while popular altcoins often spike 20% within a day. If it were to drop more than 30%, it would have to be a black swan event.

Black swans do exist, so he divided his position into 10 parts, each worth 1,000 U, locking the rest in a cold wallet—first ensuring he wouldn't go broke, then talking about making money.

The specific operation has only three steps:

1. Choose the track: only focus on the top 3 to 5 hottest altcoins of the week, selected if they make it into the top 20 based on trading volume, Twitter trends, and GitHub updates.

2. Wait for the signal: a 4-hour level breakout of the previous high + MACD golden cross + negative funding rate. Open a position only when all three conditions are met.

3. Roll the position: Start with 1,000 U at 3x leverage, adding 30% of the original position for every 15% profit, while transferring equivalent profits to the 'insurance account'.

The money in the insurance account never re-enters the market until the entire principal is recovered; the remainder is pure profit in motion.

The craziest A Shu got was rolling from 1,000 U to 18,000 U in 19 days. During that time, he faced an 8% pullback without even looking at the K-line—his profits were substantial, and his mindset was as steady as an observer.

Conversely, if a particular order were hit by a black swan, the maximum loss would be 600 U, equivalent to 4,200 CNY, the price of a plane ticket, not affecting his continued travels.

Later, when the market became chaotic, he impulsively lost hundreds of thousands in one trade. Fortunately, he had a solid foundation, and six months later, he filled the hole again using the same discipline. He summarized:

'Altcoins are not a belief, they are a tool; leverage is not a flood, it is a wrench. Using tools to the extreme, it's possible to achieve great returns from small investments.

The worst is treating 1,000 U as 100,000 U and treating 3x as a 20x gamble—that's not investment, that's jumping off a building.'

Now, A Shu has reduced his single position to 300–400 U, with 3x leverage, continuing to surf while rolling positions.
