Well, even if not keeping everything in Bitcoins (which, I agree, sounds dangerous) the same scheme can be used as a convenient cash alternative that - unlike many credit&#x2F;debit card payments - preserves privacy. I mean, I rarely want merchants to know my full name or email or whatever, however cash isn&#x27;t always convenient. The transaction fees aren&#x27;t great, but it&#x27;s still looks like a fairly nice option.<p>(Offtopic) And, sorry, I had just fat-fingered a downvote when I meant to upvote!
