This is a story about looking at the root line, regardless of how much water it contains, just a simple entertainment small reference.

If I make enough 50 million in the crypto circle, I will choose to stop: this profit system should be sealed away!
A decade of hard work in the crypto career, from the 20k principal I saved up in 2016 to the assets that now allow me to lie flat, has never relied on luck.
By then, this profit method, praised by crypto friends as the "Eternal Profit System," should also be sealed away along with my retirement.

The core of the system is "Three Lines Determine the Universe."
Open the K-line chart, always look at only three lines: the 50-day moving average determines the short-term trend, the 200-day moving average identifies the bull-bear boundary, and the volume line judges the authenticity of funds.
In 2017, when Bitcoin broke through $5,000, the 50-day line just crossed the 200-day line, and the trading volume suddenly increased to three times the six-month average.
I mortgaged my wedding house with 3 million and went all in, and that bull market made my account break 20k for the first time.
The iron law is like a fuse for the system, indispensable.

Iron Law 1: No more than 15% of holdings in a single coin.
In 2018, when Litecoin surged wildly, I only invested 12% of my position according to the rules.
Even when it later fell 80%, it didn’t hurt my core.
Diversifying holdings is like installing shock absorbers for wealth; no matter how crazy the market, it can’t shatter the principal.

Iron Law 2: The stop-loss line is the last line of defense.
Mainstream coins breaking below the 50-day line by 8% must be sold, and altcoins breaking 5% must be run away from.
On the night before the Luna crash in 2022, the system automatically triggered a stop-loss.
My 1% position only lost 70k US dollars, while some around me were in debt for tens of millions.

Iron Law 3: Only 3 trades per month.
In early years, I always tried to catch every fluctuation, but ended up losing half a house due to frequent operations.
Later, I forced myself to make no more than 3 trades a month, which helped me seize key moments like the 2020 crash and the April 2021 correction.
The last trade was last week.
Ethereum’s 50-day line touched the 200-day line for the third time but didn’t break below, and volume shrank to recent lows—this was the "golden buy point" given by the system.
I entered with 8% of my position, and when it rose 15% in three days, I took profits according to the rules, just enough to push the account past the 50 million mark.

While tidying up the tea table, I found my trading log from 2016, with the front page written: "Retire after earning 50 million."
Back then, I was drinking porridge in a rented house in Guangzhou’s urban villages, watching the charts, never imagining I could really wait for this day.
Actually, the secret to profit was already written on the last page of the log: "A complex system earns money from emotions; a simple system earns money from time."

As for this system, perhaps it will be carved into a USB drive and thrown into a cabinet—
The money in the crypto world is endless, but life should have scenery more worth watching than K-lines.
After all, true financial freedom is finally having the confidence to tell the late-night market watch: "Goodbye, no need to see you again."
