If Satoshi Nakamoto tell the mysterious truth about his Bitcoin and Blockchain invention and all the secrets to the media, how will it affect the Bitcoin Price ?
There is no secret in bitcoin.
It is open source and all code is available. Which is why we like open source software. If Satoshi chose to reveal him/herself, it would not change anything about how bitcoin functions. I think it would be foolish to re-value coins based on Satoshi.
