Recently, I've seen many people asking what exactly liquidation in cryptocurrency means, so I might as well organize my understanding.

Let's start with the basics. Suppose Bitcoin is now $50k each. If you buy one directly, that's a regular trade, nothing special to say. But leverage trading is different. You buy one Bitcoin, and you might only need to put up $5,000, with the remaining $45,000 borrowed from the platform. That's tenfold leverage. Sounds great, right? Because if the price rises, your gains are amplified ten times. If Bitcoin goes up to $55,000, and you sell, paying back the $45,000, your $5,000 principal doubles.

But there's a deadly problem. If the price moves in the opposite direction and drops to $45,000, your situation becomes very awkward. At this point, your assets plus cash in your account just cover the amount owed to the platform. In other words, your $5,000 is already wiped out. At this moment, if you want to gamble on a rebound, refusing to sell, but the platform won't gamble with you. They need their money back, so the platform has the right to forcibly sell your coins, directly recovering $45,000. If the price continues to fall to $44,000, not only do you lose everything, but you also owe $1,000, which is what we call liquidation.

How can you avoid liquidation? There's only one way: add more funds. Deposit another $5,000 into your account, so your total assets are higher than the borrowed amount, and the crisis is resolved. But this is already very harsh for retail investors.

The truly terrifying part is that, in unregulated, unscrupulous exchanges, liquidation might not be caused by market natural fluctuations at all. I've heard stories where these exchanges hold all investors' position data, knowing at what price you opened your position, how much leverage you used, and even when you're sleeping. At midnight, a few big players working together, wildly pushing prices higher. Sleepy retail investors don't have time to add funds, and traders with tenfold leverage on short positions are forcibly liquidated. At this point, only a small amount of capital is needed to push the price up because most people are asleep. As the price continues to rise, more short positions get liquidated, and their automatic liquidation orders help the big players keep pushing the price higher.

Suppose the price crashes from $50k to $75k; all short positions with more than five times leverage are wiped out. If the big players also use tenfold leverage, they can make four times the profit from this move. Even more crazy, after pushing the price down with short positions, the big players can immediately switch to long positions. By wildly shorting and dumping, they drive the price back down to $50k, causing all retail longs to be liquidated again. All trading data is real, but the result is that retail traders lose money whether they go long or short, while the big players profit handsomely.

This is why understanding what liquidation in cryptocurrency means is not just about understanding the mechanism but more importantly about understanding the risks. Retail investors need not higher leverage but a sense of respect for the market. Choosing legitimate platforms, controlling your positions, and using leverage cautiously—these basic skills are key to surviving longer.

If you want to develop long-term in this space, welcome to exchange ideas. My homepage has more content, and we can discuss strategies for futures and spot trading together. But I must clarify: I won't tell you that a certain coin will definitely go up because that’s irresponsible. Our discussions should be based on rational analysis and risk management, not blind speculation. I hope our encounter can maintain the sincerity from the beginning.
