Bitcoins are very recognizable. It's a fact about the world that they are currently unrecognized.
Agree. I was more referring to the fact that most mainstream people can hardly wrap their head around paypal, much less bitcoin. Yet paypal is far more recognizable as a products/brand. I changed it to a C-.Quote
Other than that I disagree about auditability. If you want to open your records how is that hard? Oh, I guess you can't prove that you don't have another address with more money than you are claiming, is that all you mean?
By auditability, I meant it would be nice to do instant "approval" for transactions. Eg, if you are supposed to pay me 30 BTC from an account you specify, it would be nice if I could check that account and make sure that you have at least 30 BTC in it, ideally without revealing your full balance. Just thinking out loud here. Maybe we should get rid of this property requirement all together?Quote
Anonymity doesn't seem to warrant an F at all, if you have a way to earn anonymously, you can spend anonmyously pretty easily. And even if people knew you had the coins at some point it's easy to flip them out for different ones at mtgox or something. Then they would need mtgox help to get you, but you could also do it three other places.
I was probably too harsh here. However, currently with bitcoin your transactions are easily traceable unless you choose to obsfucate them. I'd like something the other way around: untraceable, unless you explicitly choose to divulge transaction info (much like physical cash is today). I changed this to a CQuote
What would you rate PP on anonymity? F- I guess, are they really that similar?
Good point. PP would definitely have been the F, not bitcoin. Changed bitcoin to a C, since it takes some serious effort to remain anonymous.
