that's the reason why i like to use and to pay with bitcoins, miners fee is like, 0,00004 bitcoins?anyway, it's really really small, not even 1 cent, while paypal and ebay fees are around 14% if i'm correct, that might be reason why bitcoin will be main currency later
It's because these party's people are fed up. Fed up with CC/Paypal and this expensive market places.
They take too big of a fee which make selling small or cheap items a waste of your time because the fees cut your profit.
I am positive more and more people will see this.
