he's creating altcoins now
The only time I thought that was reading the cryptonote wiki:
https://en.wikipedia.org/wiki/CryptoNote#Origins Its really cheesy to say something is "the next project from Satoshi" but CN does sounds like a natural evolution.
Definitely not running an exchange.
As far as an alt-coin, only if it has some unique new features which essentially none do. Not ethereum, he wouldn't launch like that. The dark coins - not enough of an improvement.
Satoshi is around, just not doing an exchange or alt-coin.
I like the idea that he created CN coins.
Being able to spend coins silently mined in the beggining without whole world waching seems a vast improvement
