All your post have to do with trying to gain bitcoins from selling those things, why don't you just try selling those things at a better price, remember bitcoins is on a rally currently this means you can take a low price and make up the different in the rally, so while you may only get 30 bucks worth of bitcoins you can double into in the $60 over night.
$30 to $60 overnight? How would you do that without leverage?
