LOL, I would not invest with such a club where the chairperson decides what to do with the our money.
You correct, everyone contribute an amount per month. Once the 'goal', lets say R10,000 is reached, then that money is invested. But the choice of investment is made by all the members/partners, not the chairperson alone. So any one can come with a suggestion for a investment, and the partners will vote on it.
Something like that! Please ask more questions!
