“80,000 down payment, $450 per Bitcoin, I didn't even blink and went all in.”

When my friend heard this, the chopsticks fell directly onto the table: “Are you crazy?”

I laughed lightly, but inside I felt like a firecracker had gone off — the huge bang in 2018 blew me from the beach in Phuket into the abyss of a bear market,

then blew out four life-saving iron rules. Today we'll first talk about fireworks, then pass the lighthouse; those who want to come ashore, follow me on the last sentence.

1. Only make money that you understand.

The first loss was in NFTs. The big shot shouted, “A picture will multiply ten times,” and without even clicking on the smart contract, I rushed in with 250,000.

Three days later, the picture was still there, but the money was gone. At that moment I understood: outside the circle of cognition, it's not a gold mine, it's a crematorium. From then on, I only wrote code I could understand and only invested in projects with clear logic.

2. A steady position means a good night's sleep.

The illusion of getting rich quickly burns money the most. I divided my position into three parts: 50% anchored in BTC and ETH as digital real estate; 30% for inter-period arbitrage to earn stable price differences; and the last 20% in a cold wallet, with the keys around my neck, ensuring I wouldn't starve no matter how fierce the market was. At night, I dream of the sound of waves, not liquidation alarms.

3. Leverage = sickle, not touching it is earning.

On that glorious night of contracts, I had 20x leverage, with a paper profit of 870,000, but then a single 8% needle brought my account to zero.

Before deleting the app, I took a screenshot and set it as my phone wallpaper — if I felt impulsive, I'd look at it first. After half a year, I preserved the principal and didn't go crazy.

4. Only trust on-chain data for news.

Before the LUNA crash in 2022, the on-chain locked positions evaporated by 70% in three days. I cleared my positions ahead of time based on the data, and looking back, my friends were still entering the “century's golden pit.” Signal groups and KOL tweets were all smoke and mirrors; data is the true track. Don't run blindly with your eyes closed; you need to see the traffic lights clearly.

Four years have passed; I no longer count stories of 100 times but write my ledger based on a 20% annual compound interest. In the cryptocurrency world, running fast doesn't count as a skill; going far makes you a winner.

If you are also tired of the rollercoaster of skyrocketing and plummeting, and want to exchange your torches for streetlights — @番茄说币
