I bought coffee at the Prague cafe that only accepts bitcoin. Here’s what it was like.

The process was actually really easy. I didn’t even need a smartphone. The first step is to get a bitcoin wallet. Initially it is empty and has no value.
The paper wallet contains two unique numeric codes. One serves as your public key, which allows you to receive bitcoins. The other serves are your private key, used to spend or send payments. Each code is also transcripted within a corresponding QR code located next to the code for easy transfers using QR scanners. As a backup, I wrote the private key down somewhere safe.
