Pizza for bitcoins? by laszlo I'll pay 10,000 bitcoins for a couple of pizzas.. like maybe 2 large ones so I have some left over for the next day. I like having left over pizza to nibble on later. May 18, 2010, 12:35:20 AM So nobody wants to buy me pizza? Is the bitcoin amount I'm oering too low? May 21, 2010, 07:06:58 PM I just want to report that I successfully traded 10,000 bitcoins for pizza. Thanks jercos! May 22, 2010, 07:17:26 PM Bitcoin Market 10kBTC = $41 jercos 40.
