After spending a long time in the crypto world, the most common question you hear is: How much leverage should I open for perpetual contracts? n Many people think this is a math problem, but actually it's a cognition issue. n nPerpetual contracts have no expiration date; theoretically, you can hold an unlimited position. This gives traders flexibility but also lays a trap. Being able to enter and exit anytime is indeed satisfying, but that temptation—using small capital to leverage huge positions—is the easiest way to get wrecked. n nLeverage itself has no absolute safety standard. What is the real difference between 30x and 100x? It’s just the reaction space the market leaves you. The former gives you a few centimeters of buffer, the latter only a few millimeters. But if you only play with 500 yuan to control a position worth tens of thousands, no matter how many times you leverage, the outcome is the same—any market fluctuation can knock you out. n nThis is the most heartbreaking: seeing the right direction but being swept out by volatility is even more painful than seeing the wrong direction. n nSo what is the real answer to the question? It’s not the multiple, but control. n nHow do experienced traders do it? n nFirst, only use isolated margin mode. Full position is suicide; isolated margin can lock risk within a single trade. n nSecond, set a stop-loss. Don’t think about "holding through." Holding through often leads to liquidation. n nThird, set a small daily goal. Is it a problem to earn 50-100 yuan daily with 500 yuan capital? No. It may seem insignificant, but the power of compound interest is here. A monthly return of 20%-40% is top-tier performance in any financial market. n nLeverage is ultimately a magnifying glass—it amplifies not only gains but also your discipline, greed, and execution. True veterans understand: liquidation isn’t the market’s fault, it’s a mindset issue. A disciplined 100x is far safer than a planless 5x. n nLeverage numbers themselves have no absolute "should," only whether they match your ability. In the crypto world, leverage is never the main character—greed is.
