1. Control your mindset in the cryptocurrency world: Do not judge success or failure based on a single trade; do not overly dwell on the gains or losses of one trade. Be resolute and open-minded.

2. In the adult world, once you buy, you must let go; closing a position is acknowledgment. The cryptocurrency market does not operate on assumptions, nor is there a 'what if' scenario. There is no room for regret.

3. Trade with a plan, remain calm in a crisis.

4. Plan your stop-loss and take-profit levels before placing an order, and strictly adhere to your plan without harboring any thoughts of luck.

5. Maintain strict position control. In the cryptocurrency market, profits and losses fluctuate; do not easily allow yourself to miss out on recovery opportunities. Additionally, heavy positions can easily impair judgment and emotions, causing missed profits and leading to holding onto losing trades because you cannot accept a stop-loss on a large position, often leading to liquidation.

6. Do not stubbornly hold onto losing trades; market movements cannot be overcome by willpower and determination. Timely stop-losses are the best protection for your principal. Even if you have enough margin, holding onto a losing position can cause you to miss out on more profitable trades, making it easier for your emotions to spiral out of control and lead to poor judgment, often influenced by personal biases.

7. Remember, never let trading in cryptocurrencies affect your normal work and life. Whether it's contracts or spot trading, it inherently carries risk, so it should be based on a certain economic foundation and time commitment. If you do not have sufficient financial backing but have some spare time, it’s perfectly fine to invest a small amount of pocket money to gain some experience.

Apart from professional traders, most people trade cryptocurrencies merely to add an extra income to their otherwise dull lives.

Furthermore, whether it is spot or contract trading, there is no guarantee of profit. Many people enter the cryptocurrency market after hearing stories of astronomical returns; indeed, there are many cryptocurrencies that have multiplied a thousand or ten thousand times. Many have reaped such rewards, but remember they typically invest spare money, and often forget about their investments after purchasing, which allows them to achieve such immense profits.
