But, your average joe... what is he going to buy? Computer parts? probably not.. Speculation investments? probably not.... Drugs... More likely than not.
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.
Well then... Why wait. certainly the bush has been beaten near to death with insinuations.
I would like to officially make the claim that to the average joe bitcoins are highly useful for buying drugs and other illegal items.
