On a video chat with a casual professional group (SJ npub1jrxw5cqv6ej7kdg0fys8s2qaf2sv5zquplycueg48j7av6crmstqzvcrhp is part of that group), and we have a cyber security insurance guy on as a speaker. The two things I really see as not solvable with Bitcoin is social engineering and bad IT security. Stealing keys will be a real thing, and getting people to send Bitcoin to the wrong address will be, too. There's only so much you can do to help others keep their coins secure.
Air gapped hardware wallets will prevent bad actors from directly accessing it, but they can still send fraudulent invoices to the company accountant or owner, and fake emails can be sent with fraudulent payment instructions.
What have you thought of to combat social engineering? #askNostr
