OK, seriously, how does paying with BTC actually work?

I want to purchase the Where Winds Meet cheats.

 

I've never used BTC to pay for anything and the process is a bit confusing. I can't use Google Pay or my debit card because my currency is USD, not the euro.

 

I have more than enough bitcoins to pay via crypto through my Coinbase account. I see the invoice that was generated on this website for me to pay, and I see the "pay in wallet" button on that invoice and it opens a new tab that doesn't actually load anything except a URL at the top.

 

I can manually transfer the bitcoin from my Coinbase account to the supplied address, but how does the system here know that I paid the invoice? How do I prove to administration that I did pay to receive these cheats? If I send the bitcoin manually to the address on the invoice, does it detect the payment received and the invoice will be marked as "paid" or what?

You don't prove anything its all automatic
get BTC on your coinbase account, then on checkout send to the address it tells you to together with the amount needed (cover fees up if there is any on coinbase)
and thats it
