# Eight Years in Crypto, Did I Really Lose 3 Life-Saving Rules with 3 Million?

In a rental in Shenzhen in 2018, I turned 300,000 yuan into nearly 3 million. Could I really defy the odds and change my fate? But three days later, the market collapsed, and before Christmas, my account was left with less than 600,000! Who would have thought that the obsession with "breaking even" could be more deadly than liquidation?
After eight years of ups and downs, I paid a heavy price to learn 3 ironclad rules:
1. Leverage is a knife, not wings! I once made 400,000 yuan daily with 20x leverage, but on May 19th, I lost 600,000 in two hours! Now I strictly limit: leverage no more than 3x, single-coin position ≤5%. Isn't slow the fastest way?
2. Who dares to find a family heirloom in a casino? Heavy position in "domestic Ethereum" with 250,000 yuan aiming for 1.5 million, but I almost lost everything! Now, 85% of my funds are only in BTC and ETH, 15% in altcoins just for pocket money. Is this the survival logic?
3. Stop-loss, isn't it the last dignity? Every trade has an 8% hard stop-loss; if it hits the line, I walk away! Before doubling, ask yourself: if your account is wiped out, can you still calmly enjoy hotpot?
The crypto world is never short of opportunities; what’s missing is the capital to survive until those opportunities come. I crawled out of the ruins, abandoned the illusion of quick riches, and only kept a faint hope of survival. Isn’t this the harshest truth in crypto?
