This is hard to say. Mainly depends on whether the hardware in your hand has been replaced with new hardware, and secondly depends on whether the hardware performance in your hand is far behind the new hardware.

Generally speaking, after one year, the warranty period of the hardware in your hand has passed a lot, and these will lose a lot of money. There are also some key components, such as graphics cards, which will lose a lot of price when used high. I hope there will be no updated technology. If there are new technologies, there will be a lot of old hardware in price reduction.

Generally speaking, the CPU memory graphics card is the most valuable now, but if a new generation of things comes out, the price will drop quickly, and the hard disk, especially the SSD hard disk, will be worthless, because the usage is critical to the life.

Generally speaking, after one year of use, the price is about 60%~75% of the purchase price. There are exceptions, such as memory. If you buy a lot of memory in 15, you will hoard it. You can make a lot of money by selling again this year.
