I'll try to explain.
Eg, mobile phone I bought recently redmi 4A is RM500 from Lazada. Cashback I checked from this app is 5% which is RM25. Convert to USD is RM25/assuming 4.5 is roughly USD 5.5. from what I see in the app I am using, I will see 5555 coins.

I think I can add this in the Q&A.

Don't give wrong info if you didn't use it. I have been using it 2 months already. Eg, if you buy RM 100, and cash back is 10%, u get rm10. This RM 10 is converted to coins systems. When u redeem, the amount of coins is convert to RM 10 again.
