I looked up their site to find out why they built a statue of a person they do not know his face, identity, gender, etc.
I guess the reason why Gergely Réka and Tamás Gilly might have made the statue faceless could have been as a result of the anonymity which the Bitcoin white paper portrays about Satoshi Nakamoto, been an individual whose identity not known to the public, and that might have been the reason why the scrupture was made halfway, since Satoshi's gender isn't known to the public.
The love and admiration for people with the creator of Bitcoin was born because people had realized how meaningful Bitcoin was so that it gave birth to a work in the form of a statue.
And Bitcoin still remains valuable, which is likely to draw attention to Hungary, been a city that host the first statue of Bitcoin.
