gotta be careful with it. i found most bitcoin wallets want a lot of personal info and want you to up load your state id. so how is this really any better with privacy. i know, they don't give that info out, so it wouldn't really be any different than any other method nor necessarily safer, unless you choose the right wallet.
i'm not trying to discredit bitcoin, just letting you know some of the wallets get very personal, which is more than me just giving cc number and address. still, haven't tried because circle wants a debit card.
