Here are some hints;
1. Interests; How much % they offer? Higher the better? Not necessarily. Because there is risk the bank might bankrupt. Careful with too high rates. How to calculate interest? We learn next time
2. Fees; What’s minimum deposit amount? They charge annual fee?
3. Other features; Free ATM card? Some banks give you discount for cafes and restaurants!
4. Convenience; important. Branches should be near your home or office so you can go anytime.
Better to have more than one account.
