It’s amazing.
Start with setting up an account at bull bitcoin. Use a burner email account that you only use for bull bitcoin.
Then you select buy tab, find the QR code and take a screenshot on your phone.
*you might have to use a photo editing app to shrink it a little so they can scan it.
I keep a copy of the QR in its own album in my phone for quick access at the post office.
Hand them some cash, they’ll give you a receipt saying it worked.
Then you just log into your account and click buy bitcoin. Paste in your bitcoin address.
*you need at least $100 to use the bitcoin network. Otherwise it’s lightning.
Hope that helps. It’s life changing.
