1. essentially many banks offers perpetual card fee waiver
2. the long interest free period is only applicable for the first spending, or no previous outstanding.
3. if we need to spend for 10k to get 20 back, we should firstly think of why we need to spend the 10k, instead of how we earn the 20
4. Card companies and their intermediaries are not charitable organizations. They will earn some transactions fee along the spending channels from acquiring bank, visa/mc and the issuing banks, in between, they will impose some cost especially on the exchange.
5. Often investment should use spare money, instead of money to be earned afterwards because it is not easy to bear the market fluctuation if the money is not spare |
