Hi, i would like to enquire about versa 4% for the first 30k.

For example, if I deposit 30k, one month later, the balance in my account is 30100..(30k principle, 100 interest from 4%).
The following month I will only get 4% interest from 30k and 2.5% interest from 100 or I just get 30k 4% interest?
