For BOC Smartsaver, the extra bonus is based on fulfilment of the individual conditions, ie its not like UOB one which is all or nothing. For UOB One, you dont get the bonus at all, if you fail either condition.
For BOC Smartsaver, there's no harm testing out your thesis. What's the worst that can happen? You dont meet the particular condition, and cant get the money to eat HDL or DTF lor, but you can still get bonus interest by meeting the other conditions.
i tried testing but got nothing at all today
balance only the min $200 though
