BitcoinI bought my Bitcoin from a miner when I went to the Porcupine Freedom Festival, so I have never bought it over the net. If you can visit me in Charlottetown, PE, I can sell you some in person. Or you can buy it over the internet with Mt. Gox Bitcoin Exchange.
DISCLOSURE: I have never completed an order with the Silk Road. Nor have I monitored an order from the Silk Road. Though I am interested in monitoring an order if you are considering placing an order.
