> Yeah, but this actually works. I can't use blockchain to pay pretty much any vendor I buy things from without an intermediary - the intermediary requires me to log in to a website and unless I'm willing to go through a lot of trouble (more trouble than dealing with PGP) an intermediary will also be storing my wallet and have "physical" control of all my "coins." Blockchain works to the extent that you aren't really using blockchain but simply a trusted intermediary. If you're actually personally managing your wallet keys it's worse than PGP. With PGP if you lose your key you just say so and people figure it out, you have to go to some key signing parties. With Bitcoin if you lose your key you have no money, end of story, no recourse.
