If you’re thinking to save up via Digital Bank, you may try to use Maribank. When opening an account, you can use my Referral Code: NP750516, and when you maintain atleast Php 1,000 for 3 days, you will earn Php 150.
I use Maribank to save up money and use it for my needs- it earns at least 3.25% interest everyday, then when use for paying up food and other bills- you get cash back too.
