Actually, I believe that human nature is such that no one will hide without much sense. If Satoshi Nakamoto would face criminal liability with a long term of imprisonment or his life would be in danger, then his secrecy and anonymity would be true. But if there is no danger to this person, then most likely this person has long passed away or Satoshi Nakamoto never existed at all, and under this name a group of bitcoin developers may have been hiding. And as always, my words are just one of hundreds of thousands of assumptions.
There are a lot of people saying that Satoshi Nakamoto is already died and leave his bitcoin for over the place in the internet and also there are a lot or rumors too that Satoshi Nakamoto is alive and he are just hidden into the world of internet and waiting to the right time to show again but on my side I think he are still alive and manage and control the market price for over the time because a creator is always a creator even you already got a final project and development on your creation still you need to control and manage this too because it takes a lot of updates and maintenance on the process to make sure it is stable and does not have many errors and bugs.
For me, this whole Satoshi story looks very political. After all, while we believe that Satoshi is not one person but a group of people, the impression is created about the features of Bitcoin as an international means of interaction between people. But as soon as we find out who exactly is behind its creation, and if some structures are involved in this, then bitcoin may lose some of the people's love due to media attacks on it.
There is a chance Satoshi Nakamoto is a group too because a developer and a genius and computer programming cannot handle this kind of huge number of programming systems and it is hard to handle this kind of many users and transactions happens with the use of their creation.
