I don’t care if I miss out. I’m planning on holding these as part of my FI allocation long-term. Looking (briefly) at historical performance, I expect iBonds to do as well as any other fixed income investment, even if (when) the rates drop.
I love my i-bonds. But did read a post by someone disappointed when they didn't get the November rate on their tax refund bonds. I almost sold mine when they went to zero interest (deflation), for one or maybe two periods, but glad I held on!
