#比特币市场波动观察 suggests dividing 1000U into 10 parts, using 100U for each transaction, with a leverage of 20 times. For beginners, do not use excessively high leverage; 20 times leverage is already sufficient. If a loss occurs, avoid blindly adding to your position; first reflect and summarize your experience, then make adjustments. If the funds shrink to 900U, divide it into 10 parts and continue operating. **When profits reach 300U, keep 100U as principal, withdraw 200U to consolidate profits**, and avoid leaving all profits in the account.

**Position management and risk control:**

In contract trading, fully invested positions carry significant risk, especially when using leverage. For example, with 10 times leverage, a 10% drop in price could lead to liquidation. Therefore, position management is crucial. Reasonably control each position to avoid excessive investment in a single transaction.
