I don't see how that relates to the point you were making. Clarify?
> Bitcoin as a currency is fairly useless unless you're buying drugs or you're a botnet operator
You claim that Bitcoin is useless. This was to justify the point you made before (nothing will settle in Bitcoin) or maybe as a cheap dig. Either way, your statement as it stands is worded to be condescending and confusing.
It's like saying "Mouthwash is fairly useless unless you don't want bad breath." Turns out, the market for people who don't want bad breath is pretty big. Calling it useless is wrong.
