Used my old device for two and a half years, the first time I made money I bought it, and I’ve been reluctant to upgrade ever since. Last night, while trading, it suddenly froze and couldn’t turn on, and I lost 7000U. It hurts. Now the motherboard has been sent for repair, and this incident made me realize I need to properly upgrade my work equipment. Stable hardware and environmental protection are really crucial for trading; otherwise, it could cost real money in minutes. I plan to take this opportunity to upgrade in the next couple of days and stop messing around.
