There are those who swear if you cash them in and buy new ones every

indeed makes an interesting thought experiment. most computer ones I've
looked at start with a seed number then basically count from that to
when you hit stop. You can then have the seed tied to something weird
like the number of cosmic rays detected, or the number of frames that
have been viewed on a computer since the program started and all sorts
of other things. You can sort the numbers with one random algorithm and
read them with another etc etc, but really, in the end you can still end
up with sequential numbers in a sequence, just because its as random as
anything else is!

The problem with cashing them in every 2 years is that you have to wait a
month before the new bonds can be entered in the draw, which potentially
reduces your return.
