777 "I'm not techy, but I'm morally aligned with bitcoin / freedom tech." this is the quote of the year! @npub1ahe2832lq… great interview...
Another thing that thar the interviewer doesn't get is how easy it is to verify identy is using the network affect, plus verifying the public key (npub) for instance if you have a friend you know and trust and they are following someone you can see that person is real. If you have hundreds or thousands following then you can assume that is verified. Most fake ones will have very few followers.
Hope this helps.

777 Great episode Jack lots to know and think about when taking on the personal responsibility of self defense for you and your family. I liked the explanation about the insurance vs shared membership like a health share. Definitely gonna check out CCW safe. I'll probably keep my current membership plan I have and add this as well.
