6-month T-Bills are right now like 4.5% yield or so.
I mean, compared to a savings account at ING, you’re talking about $10 over the course of a year, but if you want to get started in investing, and you know you won’t need the cash, it’s pretty easy to do.
And, when your buddy asks you if he can borrow $5, you can tell him, “sorry, but all my vash is currently tied up in T bills.”
