In their words
People who crossed the cliff — not alone.
“They didn't just hand me a device. Someone stayed on the call until my seed was backed up and verified. That's the part I was scared of.”
D. FreedomRecovered a wallet “I'd watched a dozen YouTube videos and still froze. An hour with a real teacher and it was done — correctly. Worth every dollar, once.”
EvanTook the course “No subscription, no company holding a key I can't see. I own it, my family knows the plan, and it was one calm afternoon in Boulder.”
