Relatively new in this. Want to ask few questions.

1.What's the minimum amount needed to be deposited? I see PBE put up 10k while, on sites like UOB and CIMB, there isn't any specific amount mentioned.

2. Which bank offers the better rate on NZD and AUD?

3.If I put the FD for one month, will it safer than if I put it for a year long?
