Say I am running a business in Europe. And one day I need to translate some text from German to English. I go to Google and enter "German to English translation service".
Up comes a website that says "We translate one page of text for ₿0.000048". The website does not tell you where it is operated or who operates it. They state that where they are, they are not obliged to tell you where they are. Just send the coins (via Lightning Network) and your text will be translated.
Would I be allowed to use that service? Can I deduct the expense from my taxes?
