Creating a Bitcoin Bank in Less Than Thirty Minutes With a $2 USB Drive
The first thing you want to do is download the Electrum wallet to your computer. The software can be used on Mac OS, Windows and Linux systems and takes only a few minutes to download. To maximize security users should add an operating system (OS) to the flash drive. This means creating a bootable USB stick with an OS like the privacy-centric Tails or Ubuntu.
Without adding a bootable OS, wallet data may be stored elsewhere on the computer or be vulnerable to malware if your computer is infected. A bootable drive is a thousand times more secure than a simple offline installation. The next step after downloading the wallet software is to install it directly on the USB drive’s OS offline. It’s not the best idea to use the USB thumb drive for any other online applications, and the drive should be utilized solely as a bitcoin wallet, but of course, that’s optional.
