Credit card reward points expiry — what is the validity period?

I've held this card for 3 years. Quick reality check: the welcome benefit is good, the first-year fee waiver is easy, but from year 2 onwards you really have to work for the milestone benefits. Don't keep it if your monthly spend drops below the milestone threshold.

Tip from someone who made this mistake: never max out the credit limit in the first 6 months. Banks track utilisation, and high utilisation right after approval often triggers a credit limit decrease or even an account review.
