Bitcoin was created by a man who goes by "Satoshi Nakomoto", a pseudonym (most likely). This man hasn't been active on here since 2010, when he disappeared...
Well the fact that no one knows what's the real identity of Satoshi Nakamoto. If he/she/they or what's the real score.
We didn't know if he's a real human or just a something. Bitcoin is created by this and all thanks to whatever it is because we're now enjoying the first digital currency that's dominating the world.
