Thanks for sharing, you've got a unique story. It sounds like you understand the "why" of these two pieces of freedom tech better than many: bitcoin isn't about getting rich, and nostr isn't about getting famous or whatever.
That said, they're both deep rabbit holes so understanding the "how" will be important to getting what you want out of them.
Bitcoin is only anonymous (and therefore useful for hypothetically getting around sanctions) if you engage with it carefully and deliberately, in very specific ways.
Similarly, nostr posts are not immortal; the only way to guarantee their long term survival is to run and maintain your own relay, not a trivial task.
I'm hardly an expert in either of these domains, however, so I won't give more than these broad strokes. It's a vast ocean of knowledge you're standing at the edge of, happy exploring ✌
