A digital coin of the realm, which emerged during Web 1.0 and collapsed when the Internet bubble burst, is trying to take root again in the form of Bitcoin. From Duncan Geere’s Wired UK article: “Bitcoins can be saved on a personal computer in a wallet file, or stored on the web in a third-party wallet service. On the one hand, that means that you’re not holding onto it yourself; on the other, it means that it’s safe if your hard drive fails.”
