For friends trading contracts in the crypto space, have you noticed a strange phenomenon—winning always involves small orders, while losing always involves large orders?

Just thinking about it is frightening. Set a stop-loss order, and it will rebound right at the moment you close your position. Don't set a stop-loss? The price will always precisely hit your liquidation point, as if someone is specifically watching your position. This is not a coincidence; it's the rule.

To put it simply, trading contracts is not about betting against the market; it's about betting against the exchange. They control the order book, position distribution, and your hidden cards—completely clear. Winning 10 times is just a drop in the bucket; losing once can hurt you deeply.

The profit from winning 100 times, a single liquidation can wipe it all out and even leave you owing money. This is the fundamental reason why most people always lose in contract trading. It's not that you're not smart; the game itself is inherently unfair. The money in the market always concentrates in the hands of a few, while most people are just contributing fees and margin to the exchange.
