Interestingly, if you skim through the hacker forums, there are always sections on cybersecurity and privacy. It turns out that this is useful for hackers; they have entire sections on how to protect themselves, and a forum that assumes knowledge of how to store your important data so that nothing is stolen from you is not interested in this.
I support your initiative, OP. You have almost begun to cover some useful aspects. It would be helpful to have proper guides from knowledgeable people who can help in a timely manner, rather than scouring the internet and trusting those who might be amateurs in the field of online security.
Even though, the vast majority of hackers aren't hackers in the traditional sense, but use programs coded by others, and their security sections are usually quite basic. Whereas, I think given enough effort by certain users here, we might get some real useful information related to security since Bitcoin sort of attracts those sorts of people.
