there is a lot of FUD with respect to "is bitcoin or nostr really safe. cant just some come and steal it?

well, maybe a little bit history and usage outside of bitcoin and nostr:

public/private keys

when, where, and how used (on a regular basis [even besides btc and nostr])? why its secure? why even in the future secure (quantum bla bla)?

and what would really happen if it got hacked.

thanks for your work
