Those Aldorian fragments are extremly useful at the beginning, both because you can sell very well on the market (300-350 DRUBBLE each) and you need (a lot of) them to level up your own character: if you are focused on incresing your level, keeping them is the right choice :)

Also consider when you reach level 6, 11, 16, 21, etc, you get a +5 to your inventory, so if you need more space, levelling up is the easiest and cheapest way to increase your inventory!
