Diablo 4 is unlike other Diablo series games with various tradable items. Many Diablo 4 items have trade restrictions. Once you bind items in Diablo 4, you can no longer trade them. However, you can update these items by using gold to reset attributes you don’t need. This process requires a lot of gold as you may need to reset more than once for a desired attribute. So gold in Diablo 4 is increasingly important.
