I'm no financial expert, but I can offer some advice. You can save up that money and invest in a hobby. You shouldn't forget money is made to satisfy you, and there's nothing more satisfying from a productive hobby that can earn you more income. If you like painting, buy materials. If you like photography, buy Photoshop and a camera. Or even making YouTube videos
However, a small course in Forex trading might not hurt too, plus that can give you some preliminaries before you begin to invest in shares.
