Sometimes it's hard to tell whether Bitcoin is more like Ponzi scheme or a pyramid scheme.
Whatever it is, though, it isn't a currency. It's a tech stock. Each Bitcoin is really a share in a system that seems to make it cheaper to transfer things online—money, stocks, bonds, even the deed to your house—by cutting out the middleman. Well, kind of. Bitcoin doesn't remove the middleman so much as replace him with middlemen who don't make you pay much, but make society as a whole do so instead. Is this progress?
Yes, the P-word still hasn't gone away.
It's "nice" to see a segment of the media is so scared of Bitcoin as a currency, but this author would be better off making fries in a greasy fast-food place. Certainly, "society as a whole" would be better without him getting so much attention.
