sadly i don't like that book, but i like your idea of paying with bitcoins in ebay, even if it's against ebay rules
but it's awesome to see that people uses bitcoin more and more now, i imagine what will be in future, everyone should use bitcoin or atleast know about it
i don't like this book too but i also like that idea, who knows, maybe in future ebay will change its rules and we will pay with bitcoins
also there is site like purse.io you cna buy thing from amazon there using bitcoins, so that would be easier to buy book or sofrom there not from you i think
