These have been getting a bit of press lately, largely thanks to the US treasury’s sudden Bitcoin windfall post Silk Road closedown (about US$111 million worth, last I read).

Bitcoins are the sort of thing that libertarian finance speculators wet their Armanis over, and that the rest of us would do well to stay completely away from. Actually, if we could convince all financial speculation to occur in Bitcoins–rather than the actual currencies people need for actual things like food and mortgages–then I’m convinced the world would be a better place.
