As you all may have known, the new event, Lucky Dice 2, has made it easy to get lots of equipment. However, presumably this event will eventually end. One of the side effects of the m amount of equipment is that the prices have fallen from 100 Gold to around 25~ Gold each. Due to equipment breaking, these pieces of equipment will not be in circulation for the most part after they have been purchased. Thus, I recommend buying the equipment well it is cheap, and selling it awhile after the event ends in order to profit in Gold.
