People always thought the things were impossible until someone proved wrong. I guess it's in our human nature to doubt everything we never experienced. That's okay, the future will show you.
What future are you talking about? Scamers offer to freeze a person NOW, and they want for it 1 million UTN. That is, a person will pay them 1 million UTN, and they will kill him?
You seem to miss the whole point. Nobody is going to kill you. You receive a contract for cryo. It's only needed in case of emergency. Imagine someone has an illness and there's no way to cure you. Instead of dying in pain you can be frozen with the hope of some cure emerging in the future and be unfrozen. And the company has been around since 2005 and some people were already frozen. Definitely not a scam. It would be closed a long time ago if it was the case. So better DYOR before crying scam.
