I went to a site to buy something and.. they say they accept Bitcoins.. Wonderful!
So I clicked on the bubble which says "pay with BTC" and a window pops up..
It says bitpay and it's showing an address and a square thingy with lots of dots??
What am I suppose to do next?
I just closed the damn thing and ran away
The scary square thing with lots of dots is a qr-code, which you can scan it to create the payment.
On the left side of the qr-code, you should find an address together with an amount of btc.
At the bottom, there should be a timer counting down from 15:00.
To complete the trade, you need to send exactly that amount of btc to that address within 15 minutes.
