I think we need to kill the "bitcoin requires a passport" myth as well. I have used bitcoin for 4 years and have never had to present a passport for anything.
> You brought up having to present a passport as if it were a requirement to using bitcoin
I'm not sure how you read, "a passport is required to use bitcoin" from "I've never had a bank ask me for a passport when opening a bank account". My point, which I substantiated with those /r/bitcoin posts, is that it's not unusual for a bitcoin exchange to ask for a copy of a customer's passport as part of their KYC procedures.
> One can deduce from the context that a passport is required to use bitcoin.
You deduced incorrectly. I'm saying that if the KYC system flags the recipient, for whatever reason, then they will likely be required to produce a passport.
