Imagine that in order to get bitcoins you just need to get the keys out of your pocket - and demonstrate the keychain with the QR code. This idea was born to the redditor Ch00f, who didn’t limit himself to thinking, but carved a real keychain with a metal cutter .

First of all, he generated a beautiful address for himself using the Vanitygen program. The program allows you to specify specific words that you want to include in the address. These can be their initials, last name or nickname. Ch00f has introduced its last name to the address. Finding the right address took about six hours on the video card Radeon HD6970, that is, only 0.5 trillion options, we can say that it was lucky.

When you have written down and hid the secret key, you can use any online QR code generator to encode the address. After increasing the contrast in Photoshop, the author uploaded the image to the CamBam program, selecting a milling depth of 0.5 mm.
