Win big, indulge yourself; lose, live peacefully. The biggest fear in life is not falling down, but standing still.

The contract rollover strategy in the crypto world, to put it simply, is crazy. Some people have made up to 990,000 through it, while others end up with a margin call and zero. This is completely different from the steady pace of long-term holding—rollover either makes you rich overnight or wipes out your capital. Happiness and despair are separated by just a line.

The most aggressive attempt I tried was when my account had only $1,000 for food, and within three months, it grew to $100,000. The strategy isn’t that complicated: high leverage, profit reinvestment, and sticking to one direction. I started with $300 to test the waters, opening 100x contracts with only $10 each time. Every 1% profit doubled my money. I withdrew half the gains and kept the rest going. After correctly predicting 11 directions in a row, that $10 turned into $10,000.

But the market never makes making money that easy. Most people fall into three traps: wanting to squeeze every last penny after making a profit and being reluctant to take profits; not wanting to accept losses, increasing leverage to recover, and eventually going all-in with their entire savings; or opening random trades without clear direction, getting played around by the market.

I’ve discovered two ironclad rules that have saved me many times: First, cut losses immediately when wrong; if you’re wrong 20 times in a row, stop and reflect—don’t keep messing around. Second, withdraw every time you make $5,000 to keep a clear head. During a particularly strong market last year, I started with $500 and turned it into $500,000 in three days, but I waited four months before I dared to act. This taught me that rollover isn’t mindless operation; you need to time it precisely and strike accurately.

Now, people often ask me whether they should try the rollover strategy. My answer is to ask back: Is a big market trend coming? Is the trend clear enough? Can you resist only taking the most profitable part, avoiding chasing highs or bottom-fishing? If you can do these, then go all out; if you’re still hesitating, it means the market hasn’t truly taught you yet.

Rollover is playing with fire. Once you choose it, don’t look back. If you haven’t thought it through, don’t get itchy. Opportunities pass in the blink of an eye—you must take the initiative.
