Yes. Note the USD figure.
Did I say that the price is only in BTC? No. What I said is that the price is in BTC
as well!
The BTC is in brackets because it's converted at a spot price, and not the official price of the invoice (and certainly wouldn't be legally recognised as the real price).
Those are of course your free interpretations... It is laughable that if some data in official document is unofficial if it is in brackets!?
Would you show me a screenshot of a similar invoice issued by a US based vendor if you purchased a product priced ONLY in USD with your GBP credit card? I would like to see the GBP price "in brackets"?
