I know you will tell me is Satoshi Nakomoto, in fact it`s not true. The only true is the username.
All technology what ordinary people use today was designed for military purposes.
EG : CPU, Digital Camera, GPS, Internet....
Maybe Blockchain was designed for this purposes olso ?
What do you think about that ?
All things happen because of purposes. Bitcoin did not create or invented it is just discovered by an individual in which now some people are using it to their daily lives.
