Is Satoshi Nakamoto really the founder of bitcoin? Then why he did not show in public? What do you think the reason maybe? He might be a billionaire by now if he showed his true identity in public.
I think he is a billionaire anyway. He/she has good reasons not to show up in public, because once you show up - some government would find a way for you to pay huge taxes, because what country doesn't want some extra hundreds of millions? And I think things can even get worse than that. Bitcoin might be illegal in your country, so then you might go to jail for creating it.
