#数字货币市场洞察 I know a guy who, five years ago, took the 120,000 yuan he’d saved up to buy a car and went all-in on BTC. Back then, each BTC was only 18,000 yuan.

In less than two years, his account had almost hit 4 million. He went to the Bund, popped a bottle of Romanée-Conti to celebrate, and really felt like he was chosen by fate.

But then came the 2018 crash, which took him right back to square one. Bitcoin was halved again and again, dropping below 30,000 yuan, and his account was left with less than 300,000. That bottle of wine is still sitting there, but he’d already moved out of his apartment and into a shared rental.

After going through all that, he set some hard rules for himself:

**Don’t touch anything you don’t understand.** He once chased so-called "mining coin concepts" and lost 500,000 overnight. Later he found out those projects hadn’t even had their code audited. Now, he reads every project’s whitepaper and third-party audit—if he can’t understand it, he passes.

**Diversification is king.** Now he splits his money into four parts: half in mainstream coins like BTC and ETH, 20% in cross-chain infrastructure, 20% in arbitrage, and the last 10% for taking high-risk shots occasionally. This strategy kept his drawdown to single digits during the 2022 bear market.

**Leverage is really not worth touching.** On March 12, 2020, he got liquidated for 800,000 on 20x leverage. The next day, he deleted all his contract trading apps and hasn’t reinstalled them since.

**Filtering information is more important than chasing information.** Before the LUNA crash, he noticed something weird in the on-chain staking data and cashed out early, dodging a disaster. He once blindly followed an "influencer’s" recommendation for a shitcoin, which eventually went to zero.

Now, he doesn’t expect to find any 100x coins. He relies on DeFi staking and cyclical rotation for a steady annual yield of around 15%. He opened a guesthouse in Yunnan, manages it during the day, and checks on-chain data at night.

He put it well: "There are no myths in this space. The ones who survive are the ones who understand the rules. Real wealth isn’t about how high your account balance goes—it’s about the calm that comes from letting time do its work."

If you’re still charging around blindly, making a little then giving it back, or can’t handle your losses, you really should find a stable methodology to follow. Getting the rhythm right will save you a lot more detours than just fumbling around on your own.
