I strongly believe that Satoshi is not a single person. Instead it is a group of talented computer scientists those who have created the blockchain technology. It is probably first ever implementation of the idea of decentralization. It's not just me, but I doubt anyone knows about this group or the person and I am sure they have done a great job by hiding their identity.

Banks are seeing crypto currency as a threat to their business especially in the areas of cross border trades where a huge volume of money gets transferred every single minute. Banks believe that blockchain can take away such business from them as cross border transactions can be very easily done using bitcoin or blockchain platform. So definitely Satoshi would be in a great danger if his identity is reveled to the world. All regulatory and enforcement agencies will run behind him because organized financial sector will push the government to do so. I am sure, he doesn't deserve it. So it is better for him to stay under cover and live a peaceful life fore ever.
