His information was not thumbsucked. Its all on their site and he did post that you have to deposit more than you withdraw.
IMO theres 2 types of users that will be on EE.
The first (and less common) is the a frequent trader that makes an income from trading. This person will withdraw frequently (daily, weekly, monthly etc). If they get an income from trading then obviously they will have to withdraw more than they deposit. They will have to pay the fee
The second type will be the people who are investing to reach certain goals. These people will not withdraw frequently so the deposit of R1 rule will be true for them. These investors will probably only withdraw on 3 occasions; reaching their financial goal (deposit for car/house, children's education, saving for holiday etc.), retirement, and emergencies. Thats probably a handful of times I see the withdraw amount being grater than the deposit amount if you deposit R1.
If people cant afford the R25pm, then dont withdraw monthly and deposit R1 monthly, and only pay R12 per year. You can find more than R12 per year on the floor of a parking lot.
