Good day guys, wanna ask opinion here, am planning to cancel this card, as it seems doesnt give much benefit anymore now, specifically for cashback rebate. Currently still have ikhwan mastercard and also citibank cashback. main usage is petrol, grocery, telco.

Benefit of cancelling,
Free up 2 extra slots in wallet.
Less montly commitment

Cons.
This card have no charge, annual fee, etc. Might just keep as back up.
Wont get 5% dining cashback. But rarely use though.
Amex might have special promotion on certain time/ period.

Any other point of view that should i consider before opt to terminate it?
Thanks in advance.
