I think he will keep hiding his identity, because there are many reasons for BTC to remain decentralized. and he has become a hero without identity
So hiding your identity will truly bring decentralization 
. The reason for hiding his identity is his privacy and you can bring changes without revealing your true identity.I know that Satoshi Nakamoto is founder of bitcoin.Right?
Yeah i guess so 
. It is easy to pretend that you can be the founder of bitcoin. I can also do a story with anyone and it is depend if they believe on me.
There is no one other than CSW claiming to be Satoshi, a Satoshi who is not willing to provide any proof to the general public and no one came forward with solid proof that he is lying rather than responding that he is lying 
. We do not need Satoshi as he left the project long back and we have good developers taking care of the project. We all know that the founder of bitcoin was satoshi nakamoto. But bitcoin was not the crypto was first ever made. But it was the first crypto that success.
Seriously did not understand what you try to explain here.
