The contract account has seen a good increase these days, growing from an initial 300U to 900U. Then I decided to withdraw 500U to shift towards spot trading. Speaking of contracts, they do make money quickly, but there's a trap that many people tend to overlook—if the profits earned are always kept in the account, they are essentially paper wealth. Over time, it's inevitable that due to a mistake in operation or a market reversal, all the previous gains could be lost in one go.

That's why I have developed a habit: whenever the contract yields good returns, I immediately withdraw a portion. The benefits of this approach are quite practical—on one hand, it truly locks in the profits, and on the other hand, it forces me to stay rational and avoid blindly increasing my position. Traders with smaller capital especially need to impose such constraints on themselves; they don't have the luxury of making many mistakes. Proper position control leads to a more stable mindset.
