re: 40% of Bitcoin Exchanges Fail; only 30% of those refund your Bitcoins...

He will tell us that the exchange operators are not part of the Bitcoin network. They are auxillary service providers who seek to capitalize off of Bitcoin users. The Bitcoin community is not responsible for any misfeasance, or malfeasance, of these entities that could be symbiotic, but turn out to be parasitic. The real issue is whether he will admit the only method of finding out whether an entity is symbiotic, or parasitic, is by trial and error. And that exposes the users of Bitcoins to risks it they want to convert from other currencies to Bitcoins, or vice versa.
