If I will pay most of my expenses via credit card, then is it correct to assume the following points?
1) My saving account interest rate will increase by somewhat (interest is calculated upon daily balance) because previously I use cash or Debit card when I go shopping, which means expenses are be deducted from my Debit Card (link with my saving account) instantly.
2) I can also earn some amount of money back because of my cash back credit card. Previously I used a debit card which offers quite lower cash back percentage than the credit card (0.3% usually at least 1%).
What other advantages are there?
Important point to assume: I will pay the Credit Card bill immediately upon receiving it, thus no need to worry about recurring interest for credit card.
