Hey, I'd be more than willing to sign up for a couple hundred years of indentured servitude if that's what it took to pay for several thousand subsequent years. But I can't afford cryonics, and the fact that no one is willing to take up that offer of indentured servitude as payment for cryonics is very strong evidence against cryonics having a noteworthy probability of success.

The nice thing about Russians (I'm from that neighborhood originally) is that they are absolutely crazy and will try just about anything. They also probably have/had second-best science culture behind US (though they suffered significant brain drain as huge numbers of educated Jews left in the last 25 years). They have less regulation and quite a few rich people with ideas. Seems like a worthwhile group to keep in touch with.
