Why separate short-term, long-term, and contract accounts for spot trading? In cryptocurrency trading, separating different types of accounts is not a simple habit, but a comprehensive consideration based on strategy, funds, psychology, and risk control. The following are the main reasons: Independence of trading strategy Short term: Pursuing short-term volatile profits, relying on technical analysis, fast in and fast out, requiring agility and execution. Long term: Based on macro trends and fundamentals, holding positions for a long time requires patience and resistance to volatility. Contract: high leverage, high risk, volatile, with a completely different logic from spot trading. If mixed in one account, short-term losses may interfere with long-term positions, or contract liquidation may drag down spot positions, leading to decision-making confusion. Accuracy of fund management Short term requires high liquidity funds, long-term requires stable funds, and contracts require independent risk funds. Mixing accounts can easily lead to imbalanced fund allocation, such as short-term use of long-term funds or contract losses affecting spot liquidity, ultimately disrupting the overall plan. Isolation of psychological stress Short term frequent trading pressure is high, and long-term positions need to be held calmly. Contracts experience emotional fluctuations due to leverage amplification. Mixed accounts may cause panic and sell long-term positions due to short-term losses, or disrupt spot mentality due to contract fluctuations. Splitting accounts allows each part of the profit and loss to be independent and maintain psychological stability. Reduce operational errors Miscellany can easily be manipulated due to similar interfaces or habits, such as selling long-term positions as short-term or mistakenly holding high leverage contract positions as spot. Splitting accounts makes the intention of each transaction clear and reduces human errors. Improvement of risk control system The contract risk is much higher than that of spot goods, and a liquidation may affect all funds. Separate accounts to ensure that contract losses do not affect spot safety, establish an independent stop loss mechanism, and protect overall assets. Improve transaction efficiency Modern exchanges support sub account functions, which can be linked to quantitative trading in the short term after account splitting, and focus on hoarding coins in the long term. Contracts are independently risk controlled, and operations are more focused to avoid missing opportunities due to chaos. summarize Separating short-term, long-term, and contract accounts is to ensure clear strategies, financial security, psychological stability, and effective risk control. This is a principle extracted from countless trading lessons that can help traders stand undefeated in the complex environment of the cryptocurrency industry.
