One, Spring 2021: The despair of betting 50,000 on Dogecoin. I will never forget that Friday night, with the lamp in my rented room illuminating the computer screen, Dogecoin surged 300% under Musk's tweet.
I gambled all 50,000 I had set aside for rent, fantasizing about getting a new computer on Monday. But late Sunday night, Musk tweeted 'Dogecoin is a scam,' and the price plummeted, shrinking my 50,000 principal to 8,000.
When the landlord knocked on the door for rent, I was staring blankly at the K-line chart. He looked at the green curve on the screen and said: 'Young man, this is similar to the lottery shop downstairs.' That day I finally understood: in the crypto space, chasing hot trends is just giving money to the big players.
Two, the birth of the rolling warehouse system: A disciplined experiment starting from 8,000. After blowing up my account, I made a decision with the remaining 8,000: no longer touch hot coins, only follow the 'three steps I understand'.
Step One: Sector selection — Refusing the temptation of trash coins.
In July 2021, when the community was shouting to buy SHIB, I discovered on-chain that MATIC's locked volume increased by 150% weekly. Checking the white paper, I found it was solving the Ethereum congestion problem — this was a sector with fundamentals. I bought 2000 at 0.5U and set a 20% profit-taking rule.
Step Two: Rolling warehouse practice — Key battles from 50,000 to 100,000
When MATIC rose to 0.6U, I made 400 yuan, and my principal became 8400. My friend laughed at me for 'making just enough for a milk tea', but I knew discipline was more important than face.
Later MATIC rose to 2.8U, and although I didn’t catch all the gains, I repeated the same method on ARB and RNDR:
Take profits every time I make 20% (50,000 → 60,000 → 72,000) re-enter after a 15% pullback (add to positions when 60,000 pulls back to 51,000) complete seven cycles in a year; my 50,000 rolled to 120,000.
Three, 2022 bear market: The lonely persistence of being in cash for 8 months. When BTC fell from 60,000 to 30,000, the community was shouting 'buying the dip is easy money'. I opened on-chain data: whale addresses were transferring an average of 5,000 BTC to exchanges daily. That night I wrote in my memo: 'In an incomprehensible market, being in cash is making money.'
There was a time I couldn't resist buying a certain 'anti-dip coin', and as a result, I lost 15% in 3 days. I immediately activated the stop-loss mechanism:
Forced liquidation if a single loss exceeds 2% (cut losses decisively at 1200 yuan) halt trading for 72 hours and review (print out the K-line charts and cover the walls) re-evaluate the sector logic (focus on Layer 2 and AI + blockchain)
It wasn't until January 2023 that I saw ETH's 30-day moving average turning upward that I re-entered the market — this time with a principal of 120,000, and when ETH rose from 1200 to 2400, I rolled it up to 300,000. Four, the day 1 million arrived: I cried in the convenience store. In October 2023, when a certain AI coin rose from 1U to 3U, I took profits in three stages, and my account balance jumped to 1.02 million.
That day I went to the convenience store downstairs to buy instant noodles, and the owner asked: 'Young man, why do you eat this every day?' I pointed at my phone screen and said: 'Today I added a sausage.' As I walked out of the store, tears suddenly fell — two years ago, I had once bought on credit at this convenience store.
Now my trading room has two sheets of paper:
On the left is a screenshot of the Dogecoin blow-up in 2021, and on the right is the flowchart of the rolling warehouse system: sector selection (fundamentals + on-chain data) 20% profit-taking rule (take out 10% cash after making money) cash discipline (rest if I don’t understand).
At a class reunion last month, someone asked me how I made money. I said: 'It's actually quite simple, just run when I make 20% and cut losses if I lose 15%, and don’t touch coins I don’t understand.' They laughed at me for being conservative, not knowing that in the crypto space, those who survive are not the ones who run the fastest, but those who know how to hit the brakes.
The last three reminders for newcomers (written on the first page of my notebook) First, safety of principal: Invest with spare money, don’t learn from my past of using rent to roll the warehouse. Second, not all-in: Split 50,000 principal into 5 trades, only risk 10,000 each for a 20% gain. Third, having cash on the sidelines is also a strategy: In 2022, I was in cash for 8 months and avoided a 70% drop.
Now I teach this method to my cousin, and he rolled his 20,000 principal up to 80,000. Last week he asked: 'Brother, how can you persist?' I remembered that night in 2021 when I smashed my computer and said: 'Because I know that without discipline, the next time I blow up my account may be the last time.'
