In the cryptocurrency market, contract trading often attracts many investors due to its high-risk and high-return characteristics. However, the volatility and unpredictability of the market also make contract trading challenging. Here is another description of your experience:

After a period of successful contract trading, I decided to give myself a "cooling-off period" to avoid making impulsive decisions driven by emotions. Despite this, I restored the function of contract trading in advance by creating a sub-account. This decision ultimately proved to be disastrous, because not only did I not get the expected returns, but I suffered a serious loss, losing more than 70 units of assets.

This failure hit me hard and made me very depressed. I temporarily withdrew from the contract market and switched to diversifying risks by regularly investing in mainstream cryptocurrencies such as Bitcoin, Binance Coin and Ethereum, as well as spot trading. Although this strategy sometimes brought gains, I still lost money overall, especially when the market showed an overall downward trend.

Fortunately, I successfully avoided a major market crash, which allowed me to retain a portion of my principal. During the time away from trading, I felt a lot more relaxed mentally, and I was no longer as nervous and anxious as before.

By the beginning of August, I returned to the contract trading market. After a month of hard work, I managed to recover some of my losses and earned back 40 units of assets. This made me a little complacent, mistakenly thinking that I had mastered the market trend. But soon, the market taught me a lesson, and several unfavorable operations in early September caused me to suffer losses again, not only losing the 40 units of assets I had earned before, but also losing an additional 10 units.

This experience made me realize that although I may have a certain understanding of the market, I still need more caution and self-control. Therefore, instead of setting a cooling-off period again, I took the initiative to stop contract trading and focus on the spot market.

This experience is a valuable lesson, reminding me the importance of staying calm and rational in the cryptocurrency market, and the need to adjust strategies and mentality in a timely manner when facing market fluctuations.
