I've made about 4k in the past 9 months from Raiz. I just chuck cash in it when I think the market is going to go up because it lets me get good exposure to the world's markets without transaction fees which commsec would make me pay to buy the etfs myself.
Good app, although looking at the prospectus the cash burn is high and it doesn't look like it'll become profitable unless it can really break into the asian markets...
