To see what the next variable rate will be. Also, if using the gift box strategy that would require 2025 or later delivery, to minimize the time between purchase and delivery/redemption in the event you want to ditch them.
I could see the gift box strategy but wasn’t clear on the reason to wait. I am selling the remaining 0 fixed rates ones this week and was gonna go ahead and repurchase. I guess I could set the money into the mm and collect the interest til April then purchase.
