I see that "Wirtland" is a purported country that exists (if that term is even accurate for a country) right now only the internet and has no physical presence. I would be highly skeptical of registering a business with them for fear among other things that it is unpredictable how another country in which you are doing business (Greece, the United States, or wherever) would handle that situation.
I would recommend considering forming an entity to operate the business in Greece, some jurisdiction that has a good reputation for operating businesses in other jurisdiction (such as Delaware in the United States), or wherever you plan to do the business.
