Hi guys,
sorry for I am in my first contact with Bitcoin, but what I am really interested in:
Is bitcoin a REAL currency?

In germany our definition of currency (in german: https://www.juraforum.de/lexikon/waehrung) is something that is controlled by an institution - so a real currency needs something that regulates it.

Does bitcoin have an institution that controls / regulates it?
Please be kind, I am really interested in this technology.
