he utilised the credit given
fund the 9.5k with credit card without forking out a single cent, cash out to repay on cc due date, then repeat this cycle
in short, there is no initial investment cost

imagine a credit card which provides cash back on ewallet reload
the return on the cash back alone is way above than the earnings from go+
(RM 80 x 12 - RM50) / RM 9,500 ~ 9.5% p.a.
if zero initial investment cost is factored in, 900% p.a. with a few click
combining with multiple cash back cards... RM 3,000 + RM 2,500 + RM 4,000, RM 1,820 p.a.

u come across any outlet that sell pin and can accept cc ?
