Many beginners hold around twenty thousand in spot assets, watching prices plunge and surge daily, feeling uncertain—wanting to preserve their principal and survive longer, but also afraid of missing out on big opportunities. Actually, it’s not that complicated.

The key point: first calculate your loss limit, then consider how to make money.

**Write risk as a hard leverage**. For example, with a million-dollar account, the maximum loss per trade should be no more than twenty thousand dollars—that’s the bottom line. Then, based on this loss amount, work backwards to determine your position size. Set tight stop-losses? Then keep your position small. Use loose stop-losses? Then lower your position size accordingly. As long as you strictly adhere to the red line, your account always has bullets to recover.

**Test the waters with the first shot**. Even if your calculations show you can open a 20% position, start with 10%. If the market moves against you, the loss is smaller; if it moves in your favor, you can add more, controlling your overall cost. Surviving is the hard truth; guessing the market correctly is just a bonus.

**Adding to winning positions is not taboo**. Don’t listen to the argument that “adding to winning positions will inevitably lead to losses.” The key is to set a trailing stop properly, using existing profits to cover the risk of new positions. Even if the market drops, you only lose the profits, and your principal remains intact.

**Go against human nature to adjust**. When your net value hits a new high, use the additional profits to increase your position; if it retraces by 5%, cut back to your initial position; if you dare to add more during a loss, you’re speeding up a margin call.

**Take profits and withdraw funds when you make big gains**. When your account doubles, withdraw 50% of the principal to your bank card. The numbers on the exchange are just on-paper figures; the real money in your hand is what counts.

**Repeat the cycle**. Stick to discipline at every step, and your emotions will stabilize naturally. The account curve will then steadily rise. Ordinary people find it hard to precisely predict the market, but with this ironclad rule, it’s entirely possible to survive longer and earn steadily in the market.
