Spend them on what? There's nothing other than drugs to spend them on.
This is a very silly statement.
I've spent probably $10k worth of Bitcoins over the past year and a half. Not once have I bought drugs.
It's not all that silly.
evoorhees has purchased very geek centric services I suspect. Bitcoin being geek centric currency, it wasn't hard to find a willing seller of geek services.
But, your average joe... what is he going to buy? Computer parts? probably not.. Speculation investments? probably not.... Drugs... More likely than not.
Yes, the OP claim was silly, because it stated that the ONLY reason to use BTC is for illegal uses. I then countered with the point that I've bought services from people which were not illegal (or anything close to it). Unless I am lying, this invalidates the OP's point completely. Perhaps he could change his statement to say a large use is for illegal items, but saying the "only use" is hyperbole BS.
And the claim has NOT been made that BTC is currently useful for the "average joe". It is not useful for him... today. Just as the internet was not useful to the average joe in 1995.
