If he would expose his identity, he would be forced to make it centralized just from the beginning of it, but he was anonymous and I think he made the right choice. Secondly, he would be the most famous person in the digital world (I'm not saying he is not but more than now). As he holds 9,80000 BTC in his wallet and there is no sign of activity on it which suggest maybe he is dead leaving this btc behind?
One thing that confuses me, he was on this forum and posted his posts about the first ever BTC token and Blockchain here, and not been active since 2010. The real question that confuses me is if he is publicly here on the media what will be the reaction of authorities? And he is the founder of this forum too.
Satoshi planned things carefully from the beginning. He knew that giving birth to an alternative currency outside the control of governments and central banks alike would not come without risks. Either such entities would've prosecuted Satoshi, or BTC would've become a centralized coin within its early days. I'm glad things worked out exactly as planned, as now Bitcoin is a "force to reckon" with. No one knows the whereabouts of Satoshi, but it doesn't really matter since the project is now in the hands of the community.
What we need to pay close attention to is Satoshi's BTC holdings on the Blockchain. If coins are moved to another address, that means Satoshi is alive. I just hope he doesn't sell all of his BTC, or that would crash the price real hard. That wouldn't affect the Blockchain's operations, though. Bitcoin has been doing fine without Satoshi, so I'm pretty sure it will last a lifetime if it remains decentralized and censorship-resistant. Just my opinion
