A DIY Bitcoin hardware wallet for $110? This developer explains how

Justin Moon, founder and instructor at Bitcoin workshop BUIDL Bootcamp, has created a do-it-yourself Bitcoin hardware wallet—that can be bought in parts for $110. The device, currently called the BitBoy, can send and receive bitcoins.


On top of the basics, it has two security features that make it stand out from other Bitcoin hardware wallets. It is stateless, which helps protect the device from losing funds, and it uses a QR-code-based, air-gapped feature to help keep it safe from hacks (more on those later). And these two features, combined with its low price and low barrier to entry, sent Crypto Twitter into a frenzy.


Moon posted a video—which has been watched more than 60,000 times—that showcases the retro-looking device and how it works. We caught up with the Austin-based instructor to find out more. Source...
