Instead of investing an amount of money based on the price of a whole share we have made it possible to invest any Rand value you like in a security you want, making it as simple as possible to invest in the companies / entities you love.
If after the purchase of a security, the price of that security increases by 10%, your Rand value will as a result also increase by 10%.
In this way, instead of measuring the company's changing price to determine your returns, you simply invest a Rand value and watch your money grow.
