It's a cash alternative - I dont see the downside like you imply. If you have a life crisis (over the next 12M) and need every penny you can get ASAP - then yes, this wont help. If inflation tanks, these current i bond series wont be of much interest either as the reset rate goes lower and lower. Even still - these beat keeping idle cash in a savings account - which is how everyone is positioning these. That is really the whole point. I'll be adding another slug on 1/1/22.
