Ok first to make 50 platinum or more per hour I would recommend having a character level 7 or higher. Now bring your character to Butcherblock Mountains now kill lots of goblins (don't bother killing the goblin whelps or any aqua goblins) now loot goblin heads and goblin blood vials. Once you have a lot go to a merchant in that area and sell them both 4 platinum each. Keep doing this and you can make around 50 platinum or more per hour.
