(Sensible if legal) Compound-interest cryonics: Devote a small chunk of your resources towards a fund which you expect to grow faster than the rate of inflation, with exponential growth (the simplest example would be a bank account with a variable rate that pays epsilon percent higher than the rate of inflation in perpetuity). Sign a contract saying the person(s) who revive you receive the entire pot. Since after a few thousand years the pot will nominally contain almost all the money in the world this strategy will eventually incentivise almost the entire world to dedicate itself to seeking your revival. Although this strategy will not work if postscarcity happens before unfreezing, it collapses into the conventional cryonics problem and therefore costs you no more than the opportunity cost of spending the capital in the fund before you die. (Although apparently this is illegal)

The rule is often stated as follows: “No interest is good unless it must vest, if at all, not later than twenty-one years after the death of some life in being at the creation of the interest." For the purposes of the rule, a life is "in being" at conception.

It seems a workaround would be to keep around a frozen embryo. Since frozen embryos are viable with current technology, they probably have to qualify as not dead. You could probably also do it via donating the money to an "independent" organization, but that's not as cool as using cryonics as a workaround to aid your cryonics.

The bigger problem is that you'll have trouble investing the money at a rate higher than inflation (and keep in mind that in the US the rate of inflation is much higher than the official number)
