In the past there was a big need for this, with minimum brokerage fees, and high percentages. But this position has mostly been filled by easy equities, who have no minimum fee. You can also own a partial share, ie if you invest R800 in naspers, you get the benefits of half the holding, someone else would own the other half. As a bonus you get to choose which shares to invest in.
As a groupon/broker I'm not sure I'd want to invest in the same thing everyone else does. Unless there is a very significant fee discount, and a rock solid company and contract protecting my assets. Can you get lower than 0.25% with no minimum?
I did fill in the survey but you never revealed what the token would one day be...
