See my reply to brokenmachine. Let's do a little thought experiment. Suppose that I, living in the USA, want to send money to my aunt living in the Caribbean.

See my reply to brokenmachine. Let's do a little thought experiment. Suppose that I, living in the USA, want to send money to my aunt living in the Caribbean. Let's also say that she has never used bitcoin (like most people) and that I don't have an account on a bitcoin exchange (like most people). How do I get her $1000 within 24 hours using bitcoin?
