One of the millennial hackers I know do this to make some spare change.
(Getpoints)
Objective is to keep collecting points via the Maybank American Express, there's a 5% cashback and 5x treatpoints on weekends. Claims he can make some small change doing this method.
This hack currently works because probably due to 3 factors.
1) Maybank wants to boost its American Express usage and hence absorb the merchant fees
2) Boost Wallet does not charge on transaction for Maybank (use my promo code : onglrwv)
3) Hello Gold cash out to bank does not incur fees. (use my Hello Gold promo code : ONGC04YH)
