Didnt look too much into it but my gut feeling based on the price says its too cheap to be able to keep the lights on for centuries.

I would rather do a one time payment because they sure wont get money from me when i am dead. So a one time payment must basically be big enough to generate enough interest/stock market returns to make it worth their while too keep the lights on forever. I dont see this with a 50€ Subscription. Maybe they would do it like an ETF Investment Account which signs you up for Cyro Preservation after reaching a certain size. The money would have to be withdrawable while being alive though.

It works through a life insurance. So it's not just the subscription.

Besides that, as far as I understand, cryonics is heavily dependent on effects of scale. My hope is that by the time I'm about to get frozen, enough people will be interested in it to make it economically viable long term.
