How to Invest in Series I Bonds

You have until about one week from now. Should you put more money into a series I bond right now at 6.89%. Now we already know that come May 1st that probably the renewal rate that you will absolutely get if you invest at 6. 89% right now or 3.45% because remember you only get half of that will be 3.38% right around there or approximately 1.89%. What I care about is that your money is locked up for 12 months, you cannot touch it no matter what. For the next four years, you cannot take your money out without what without a three month interest penalty.
