Thanks for the alert that yield coupon can only be activated on additional deposit and not on current deposits unlike Webull yield coupons which can be applied on current deposits.
Given these constraints, I would still prefer the yield coupons as each coupon is valid for 60 days so, bite the bullet . Say for titanium.
1) first 65 days just earn normal mmf yield
2) collect 2 yield coupons
3) withdraw out all the 150k
4) put back 120k apply 1 yield coupon for 30 days
5) withdraw out the 120k
6) put back 120k apply the last 1 yield coupon for 30 days
A 125 days project
What I dislike about the trading coupon is it applies for buy trades only, Min 300 transaction value and 30 cashback.
Buy and sell , 2 way commissions and bid ask, I think maybe net 23-24 sgd. 180 become 138 bucks liao.
